How to Calculate Mass Percent Composition

This is a worked example problem showing how to calculate mass percent composition. Percent composition indicates the relative amounts of each element in a compound. For each element, the mass percent formula is: % mass (mass of element in 1 mole of the compound) / (molar mass of the compound) x 100% or mass percent (mass of solute / mass of solution) x 100% The units of mass are typically grams. Mass percent is also known as percent by weight or w/w%. The molar mass is the sum of the masses of all the atoms in one mole of the compound. The sum of all the mass percentages should add up to 100%. Watch for rounding errors in the last significant figure to make sure all the percentages add up. Key Takeaways Mass percent composition describes the relative quantities of elements in a chemical compound.Mass percent composition is also known percent by weight. It is abbreviated as w/w%.For a solution, mass percent equals the mass of an element in one mole of the compound divided by the molar mass of the compound, multiplied by 100%. Mass Percent Composition Problem Bicarbonate of soda (sodium hydrogen carbonate) is used in many commercial preparations. Its formula is NaHCO3. Find the mass percentages (mass %) of Na, H, C, and O in sodium hydrogen carbonate. Solution First, look up the atomic masses for the elements from the Periodic Table. The atomic masses are found to be: Na is 22.99H is 1.01C is 12.01O is 16.00 Next, determine how many grams of each element are present in one mole of NaHCO3: 22.99 g (1 mol) of Na1.01 g (1 mol) of H12.01 g (1 mol) of C48.00 g (3 mole x 16.00 gram per mole) of O The mass of one mole of NaHCO3 is: 22.99 g 1.01 g 12.01 g 48.00 g 84.01 g And the mass percentages of the elements are mass % Na 22.99 g / 84.01 g x 100 27.36 %mass % H 1.01 g / 84.01 g x 100 1.20 %mass % C 12.01 g / 84.01 g x 100 14.30 %mass % O 48.00 g / 84.01 g x 100 57.14 % Answer mass % Na 27.36 %mass % H 1.20 %mass % C 14.30 %mass % O 57.14 % When doing mass percent calculations, its always a good idea to check to make sure your mass percents add up to 100% (helps catch math errors): 27.36 14.30 1.20 57.14 100.00 Percent Composition of Water Another simple example is finding the mass percent composition of the elements in water, H2O. First, find the molar mass of water by adding up the atomic masses of the elements. Use values from the periodic table: H is 1.01 grams per moleO is 16.00 grams per mole Get the molar mass by adding up all the masses of elements in the compound. The subscript after the hydrogen (H) indicates there are two atoms of hydrogen. There is no subscript after oxygen (O), which means only one atom  is present. molar mass (2 x 1.01) 16.00molar mass 18.02 Now, divide the mass of each element by the total mass to get the mass percentages: mass % H (2 x 1.01) / 18.02 x 100%mass % H 11.19% mass % O 16.00 / 18.02mass % O 88.81% The mass percentages of hydrogen and oxygen add up to 100%. Mass Percent of Carbon Dioxide What are the mass percentages of carbon and oxygen in carbon dioxide, CO2? Mass Percent Solution Step 1: Find the mass of the individual atoms. Look up the atomic masses for carbon and oxygen from the Periodic Table. Its a good idea at this point to settle on the number of significant figures youll be using.  The atomic masses are found to be: C is 12.01 g/molO is 16.00 g/mol Step 2: Find the number of grams of each component make up one mole of  CO2. One mole of CO2 contains 1 mole of carbon atoms and 2 moles of oxygen atoms. 12.01 g (1 mol) of C32.00 g (2 mol x 16.00 gram per mole) of O The mass of one mole of CO2 is: 12.01 g 32.00 g 44.01 g Step 3: Find the mass percent of each atom. mass % (mass of component/mass of total) x 100 And the mass percentages of the elements are For carbon: mass % C (mass of 1 mol of carbon/mass of 1 mol of CO2)  x 100mass % C (12.01 g / 44.01 g) x 100mass % C   27.29 % For oxygen: mass % O (mass of 1 mol of oxygen/mass of 1 mol of CO2)  x 100mass % O (32.00 g / 44.01 g) x 100mass % O 72.71 % Answer mass % C 27.29 %mass % O 72.71 % Again, make sure your mass percents add up to 100%. This will help catch any math errors. 27.29 72.71 100.00 The answers add up to 100%, which was expected. Tips for Success Calculating Mass Percent You wont always be given the total mass of a mixture or solution. Often, youll need to add up the masses. This might not be obvious. You may be given mole fractions or moles and then need to convert to a mass unit.Watch your significant figures.Always make sure the sum of the mass percentages of all components adds up to 100%. If it doesnt, you need to go back and find your mistake.

The Safety Regulations Of The Automobile Industry

Now days the automobile industry has to bind to a large list of government regulations. While some may just be focusing on the driver comfort and avoiding unnecessary distraction, the government has safety regulations which have to be strictly imposed on every vehicle. Within these safety regulations, there is The Clean Air Act; an act to improve, strengthens, and accelerates programs for the prevention and abatement of air pollution. But we always had criminals breaking the rules of society. VW (Volkswagen) committed fraud by having their software engineers programing the on-board engine management module (ECM) in order to obtain higher profits. Of course they did not care about the consequences neither the harm they will be doing to†¦show more content†¦It is just not in the best interest of any professional/engineer, nobody want to go to jail. It is clear that there was some sort of pressure imposed by top executive of this company on these workers. The company saw an opportunity since there is only a few diesel cars on the road. By introducing diesel powered cars that offer better mpg than gasoline powered vehicles, they knew, they were going to dominate the diesel market. It was irresponsible to use the ECM, which was designed in part to monitor the emissions system efficiency, to overlook this intended fault and provide an abstract feedback at the smog testing facilities. Aristotle made clear that all humans seek to flourish. Well, Volkswagen, as a corporation, was trying to flourish once more but not by good means. Also Aristotle pronounced that â€Å"man is a rational creature who lives in poleis† and what make society are rules, rational rules. Is these are violated, there is going to be a possibility of encountering a highly corrupted society. Aristotle thinks we should be upset if people do well undeservedly. This engineers fooled government authorities and the public for more than five years. And this case is an indignant outcome of how low big corporation can behave. The Aristotelian ethics seeks Eudaimonia or what is call happiness. This is the goal of every human

Final Paper Washington State University Political Science 418 Fall 2012 Section 1 Professor Robert Quinlan December 6, 2012 Introduction This paper is written almost exclusively with information taken directly from the book Families of the Forest  by Alan Johnson about the lifestyle of the Matsigenka Amazonian Natives. Information regarding the Matsigenka is almost solely derived from the work of Johnson unless noted otherwise. The purpose of this paper is to introduce the Matsigenka people, their needs as a community and finally pose a development project that meets the needs described. We will write a custom essay sample on Poly Sci Final Paper or any similar topic only for you Order Now Realistically this is only one possible solution posed by an inexperienced undergraduate student. The author is student who has never set foot in South America or even has had any experience with a development project. The ideas expressed in this work are purely an academic exercise. The author does not assume that the Matsigenka do not already know and or practice some of the ideas shared in this assignment. Overview of the Matsigenka The Matsigenka, a native people  of the  Amazon Basin, live in what Johnson describes as an â€Å"angular landscape, along river valleys surrounded by forested mountains†. The Matsigenka have a peripheral environment on the outside edge of conquest lands. They originally settled in to a as a bid to avoid conflicts with other groups. The land is not ideal but good enough to live on while not ever being sought as territory for annexation by other groups. They are very isolated and their living choice has the consequence scarcity. Many of the best crops, fish, and game are not as bountiful as they are in other areas. They have plenty of land for their type of farming and their small population means they do not compete between themselves for resources. Their settlements are small and spread far apart. (Johnson) To understand the Matsigenka they must be seen in their own unique context of their daily lives. As with any parent, the task of raising a child is to raise them to be able to live in the world on their own one day. For the Matsigenka this means raising children who will become accustomed to living in their own nuclear family and thrive while in relative isolation. (Johnson) The Matsigenka’s ability to be independent and desire to remain independent has been disheartening to missionaries and some schoolteachers. Attempts at organizing and building communities have largely been failures. The Matsigenka are happy to be free from directions and rules that stem from a missionary or any other persons attempt to convert or normalize them. (Johnson) From the very beginning their upbringing determines who they are as a people. From the start the emphasis on independence is apparent. No one is invited or comes to visit when a child is born. At birth a newborn is left alone on a mat while the mother is attended to. After a few minutes, the baby is then bathed with hot water causing discomfort making it cry. Johnson) The procedure is done to strengthen the child for the hard independent life to come. The Matsigenka parents test the child’s limits, expecting more and more self-reliance at an early age. In the home, mothers commonly tether toddlers to a stake keeping them from wandering into danger. The method is no more a cruel â€Å"leash† than a baby gate used in American homes could be considered a cruel cage. (Johnson) Tethering allows the child freedom and independence without the danger of physical harm. The Matsigenka’s diet is varied and extensive. Their types of food production are farming, fishing, hunting, and foraging with some small use of domesticated animals. They can eat anything from raw foods found anywhere in their environment or eat feasts involving days of preparation. The people eat insect larvae of many bugs all during the year as source of dietary fats and protein. Larger game birds, monkeys, peccary, and tapir are the favorites. Farming small gardens is the most important to them making up more than half of their food. Foraging and fishing can often time produce disappointing results. Snakes are taboo and never eaten. (Johnson) Their diet poses no issues for them. For crops the people grow manioc (cassava), maze (corn), bananas, plantains, rice and coffee. Coffee has been introduced recently by outsiders as a cash crop. Along with trying to build communities the crop was meant to bring indigenous peoples into contact and trade with the modern parts of Peru. Coffee was seen as way to introduce money into the Matsigenka system. (Johnson) Their farming methods are sufficient to sustain them and the land they work on. The most important fish in the Matsigenka diet is shima. Johnson) These fish get up to 20 inches long and can weigh over 2 pounds. They are bottom feeders caught by net fishing. Mamori are similar in size to shima and caught with a regular hook and line setup. Rock dwelling fish like etari who are caught by hand. Along with other species such as shrimp and kempiti caught in traps fit into their diverse diet. Large fish species of omani, kayunaro and char ava are rarely caught. (Johnson) Domesticated animals are not overly significant to a family. Families typically raise a couple of chickens and ducks. They are allowed to forage around the house during the day, feeding on insects considered pests like ants and sometimes are given maize. At night they are kept in chicken coops tended to by the children. (Johnson) As a people, the Matsigenka are very adaptive and catch all kinds of fish in many different ways. The Matsigenka do not participate in the market economy. Attempts to get them to raise cash crops and begin to participate have been implemented by outsiders. (Johnson) They make nearly all of the material goods used in daily life. However they do not make knives, aluminum pots or other metal items. As men and women they learn complementary manufacturing skills allowing them self-sufficiency. Matsigenka can survive in long-term isolation as a nuclear family with the skills in fishing, farming and hunting in the manner they prefer. (Johnson) The Matsigenka are adaptive, and independent. Needs and resource assessment based on the ethnographic description The Matsigenka have good nutrition and housing but they still have barriers to good overall health. The problems they have are not their fault. As a people they do everything they can like maintain standards of cleanliness, and treat illness with medicines they have available. The problems arise from limited resources and knowledge. (Johnson) For hygiene the Matsigenka clean themselves, their homes, and their clothing daily. Even when they sit on the earthen floor of their home they use a woven mat. (Johnson) They wash their hand before preparing food and are careful with waste. Baths are taken daily and garbage is thrown out in a separate area away from the home. The Matsigenka find human waste disgusting along with animal waste and believe according to Johnson that â€Å"The evil odor of feces is believed to invade the body and cause illness†(436) Families try to locate homes next to mountain streams to ensure a water supply uncontaminated by humans. (Johnson) Mountain streams, dry up seasonally forcing people back to the river for water where they are re-infected by water borne parasites. (Rainforest) Research has shown that the debilitating infections are colds, conjunctivitis, and parasites. Colds and conjunctivitis hit the community in waves. Epidemics move rapidly through the population. Tribal memories still exist of when the white man’s influenza that killed many. The people stay away from everyone and the schools when sickness hits. One of the most common greetings used by members is to ascertain if someone returning is sick and to be avoided. (Johnson) Johnson notes that researchers others who stayed with the Matsigenks stated: Most health complaints came to our attention because the medicines we had with us were believed to be more effective than Matsigenka remedies. Our house became a center where people would stop to tell us their symptoms and ask for treatment. They were pragmatic about accepting this help, seeing illness and injury as more or less naturally occurring. 436) When a family member becomes ill they are left to lie on a mat in their home while the rest of the family ignores the sick person. The Matsigenka believe sickness is life-threatening and feel a sick person is dangerous and best left alone. (Johnson) Johnson describes the Matsigenka as a mixed picture of health: They have an ample diet and are energetic and supple, capable of great feats of athleticism and endurance. They are attractive, maintain personal standards of cleanliness, and attend to their health needs with an array of remedies. On the other hand, they live with parasite loads that weaken them and probably contribute to many infant deaths, they are subject to viral and bacterial infections that periodically sweep their hamlets and incapacitate them putting food production at risk†¦ Despite the beauty of nature surrounding them and their freedom to set their own work agenda, theirs is a hard life evident in the virtual absence of elderly people. (439) A needs and resource assessment based on the ethnographic description provided by Johnson would indicate a few key items. Health education, medical aid, improvements in sanitation, and clean drinking water are the most pressing needs. These could be possibly met using a culturally sensitive and responsible means of service delivery. Development project that meets one or more of the needs described Any project design must take into consideration the unique culture of the people it seeks to help Johnson notes in a prominent way that there is family level of sociocultural integration not a community one and the Matsigenka cannot be understood or appreciated except as a family level society. Meaning, as a group they are not â€Å"tropical-forest villagers† or â€Å"tribal peoples† like most amateur sociologists may picture. Unlike other groups they do not participate in suprafamily, raiding and warfare, structured gift exchange, or even large group feasting. (Johnson) Concepts like a family reunion or organizing a militia to defend their land are completely foreign to their way of life. Johnson notes it is extremely difficult to get them to participate in any group activity. They will listen to and directions but will walk away and refuse to join the proposed group activity. Matsigenka are not amenable to being directed or led. Education or works projects from other regions cannot be rolled out in a cookie cutter fashion to help them. Understanding their independence and determination does not mean that the Matsigenka are closed to change. In the 1980 and 1970’s sierra farmers came to the mountain valleys to live next to Matsigenka families. The new farmers have brought infrastructural development that was welcomed by the Matsigenka people. They created school communities where boys, and girls, play soccer, study and do homework. Radios that can be found now are a sign of the integration of culture from the larger world around them. (Johnson) Most effective long term projects rely on ownership and the pride of the people they seek to help. Pride in ownership translates into maintenance and care of the public works project after the NGO who sets it up leaves. Johnson explains the idea of shintaro â€Å"owner† if we think of it not as legal title to objects like land or trees, but as a form of respect for the individual. Any project must transfer respect as ownership to achieve long term sustainability. Recently in the last 15 years money has been dumped into projects that have failed and been abandoned. (Fraser) It is not enough to just build something and leave. The best way to help might be to model what the rainforest flow project has done and pay special attention to some cultural factors. Any project should consider how ownership is considered, how the people operate as a family level society, the aversion to group activities, and being told what to do. The project should capitalize on their strong sense of hygiene and build on their dislike of human waste. The Matsigenka already intrinsically know about the importance of clean water and washing hands. The leap from understanding clean water and increasing the effectiveness of existing sanitation procedures should be an accomplishable task if executed sensitivly. Hygiene education and health services As a people they are very pragmatic, adaptable and have demonstrated a belief in better westernized medicine when dealing with researchers in the past. (Johnson) Setting up clinics may not be the answer since they will avoid any area where they may go and become sick. The clinic will need to come to the sick, not the other way around. Travelling to and helping sick family members on sleeping on mats in the home will strengthen any belief in stronger westernized medicine. The process will loosen the hold of traditional beliefs in bad spirits having an influence on outcomes. Health education can effectively be delivered using the existing school system and reinforced when educators visit with health professionals providing mobile medical clinic visits. (Rainforest) Previously efforts were made to do similar projects but the participants only spoke Spanish not the native language. To eliminate the language barrier it will be key that the health professionals and educators are fluent in the native language. Workers will need to understand cultural norms of the Matsigenka. (Rainforest) Special consideration should be given to immunization programs. Immunizations can make the people feel sick afterward and may scare participants off. Postponing immunizations until a trust relationship has been built up may be necessary. Credibility may be required for families to believe they are not being made sick after a flu shot or pertussis vaccination. Sanitation The Matsigenka already believe in finding the freshest water. Health education should teach how to defecate away from any water source and bury it when in the forest. The disdain they have for waste and how they conduct life around their home makes them receptive. Composting latrines with hand washing facilities may be built near schools but attention should be given to ventilation and odor control (Rainforest) considering â€Å"The evil odor of feces is believed to invade the body and cause illness†. (Johnson 436) Drinking water projects Delivering clean safe drinking water is of paramount importance to the Matsigenka, or any community. Rainforest Flow has used with self-reported success, for several years, a specific setup that uses low tech sand filtration. The method removes 99. 9 percent of bacteria from drinking water and uses a low tech gravitational flow. The systems are setup to support modest community growth and are maintained by a usage fee charged to every home water is delivered to. (Rainforest) In conclusion there are many projects that can possibly help the Matsigenka. The purpose of this paper was to introduce the Matsigenka people, their needs as a community and pose a development project that meets their needs sensitively. Like any group, assistance must be provided to them on their terms for it to be accepted. References Fraser, B. (2012, May 25). Machiguenga communities could be affected by peru gas production.

Financial Management for Merchandise and Equipment- myassignmenthelp

Question: Discuss about theFinancial Management for Merchandise and Equipment. Answer: Introduction Financial management in a nonprofit organization is significant to effectively run the business operation. It is identified that the main goal of profit organization is to earn a profit and increase the value of their shareholders. But, the main purpose of the non-profit organization is to facilitate the socially desirable requirement on an enduring basis. In current business practices, profit organization depends on exchange transaction between businesses and B2C. However, the non-profit organization depends on the money that is donated with a specific intention (Hudson, 2017).This essay discusses the financial management difference between nonprofit and profit organization. It also presents the role of Financial Management in not- for profit organizations. Role of Financial Management in Not- For Profit Organizations According to the Finkler et al. (2016), financial management is essential for both profit and non-profit organization. A non-profit organization must demonstrate the activities regarding donating resources. The workforces of the organization could be able to demonstrate their expenses activities by assessing the financial records. Furthermore, two essential areas of financial management play important role for not-for-profit organization named budgeting and cash management. Therefore, these companies focus on the utilization of reserved cash. It can be stated that estimation of cash flow is challenging for the organization because the organization heavily depends on the resource providers. In support to this, Renz (2016) evaluated that management and protection of financial resources are essential for the not-for-profit organization because, without adequate resources, the company may not attain its mission and survive in the industry. Financial resources comprise goods and services, and money. Money includes the checking, securities, investment, cash and savings that organization has required to run its business operation. Goods contain the supplies, merchandise, and equipment. Services are the program and activities which are delivered to the customers. These resources could be managed by financial management because it will decline the risks related to business. Furthermore, it will enhance the value and gain the financial resources. Bryce (2017) discussed that financial management plays important to manage the asset in the nonprofit organization. Therefore, it is essential for an organization that it should have adequate assets to fund their existing operations. They have to be competent to make stability between available and growing resources. Moreover, not for profit organization should be able to pay debts in a well-timed manner, and should accomplish other financial obligation. After creating the budget, a company can pay attention on financing the existing operation and gain resources to increase their return on capital and assets. Assets management is also required to maximize the resources. It also manages the cash inflows and outflows which help the not for profit organization to provide more benefits to communities. Consequently, it will gain significance of budgeting because the nonprofit organization would be able to attain the financial obligation. McKinney (2015) argued that nonprofit organization is distinguished from profit organization in a different manner. In this way, it stated that the main aim of profit organization is to increase the profits and transfer this profit to the director of the company and shareholders while the key purpose of the nonprofit organization is to fulfill the needs of societies. Together with, the nonprofit organization has no director and employees act with the purpose of increasing the revenue and minimizing the costs because it will ensure that company is providing benefits to societies. In favor to this, Maier et al. (2016) stated that profit organization pays tax on their earnings however nonprofit organization does not pay taxes due to not getting profit. Government helps the non-profit organization to minimize their costs because the key intention of this organization is to act with respect to the welfare of the society. Moreover, there are two kinds of organization that affected each kind of accounting practices. In case, tax exempted nonprofit organization submits their financial statement to IRS then it will only assess the sales tax and real estate tax. Arvidson and Lyon (2014) argued that financial management plays important role in appropriate managing the funds. Hence, the non-profit organization has to pay attention to the mission of the company. Further, it should monitor the progress of the company and also focuses on how capitals are being used. There are different restriction and limits that must be followed by the company during managing the funds. Since, the inappropriate use of funds can cause an extraction of money, having to reimburse the money and not getting a future return. Another cause is a loss of exempted tax and other legal problems. In support to this, Chikoto and Neely (2014) opined that a budget is an operating plan for the company. Hence, the decision regarding accomplishing the mission of the company is made by staff and board members. They have to choose the agenda that will create positive effects and then assign the resources as per the plan. The budget facilitates the steps to staffs to achieve their objectives. The budget also enables the nonprofit organization to assess how funds will be assigned and how to make optimum utilization of resources. It also helps to address the potential financial issues of the business in future. Conclusion From the above discussion, it can be concluded that financial management is beneficial for a non-profit organization to manage the finances on daily basis. Further, it enables the company to assess where donated resources are invested. It can be also summarized that there are two essential areas of financial management that are to be focused on the nonprofit organization named cash management and budgeting. Along with this, it can be evaluated that fund and asset management is significant for the nonprofit organization because it enables the company to distinguish the donated money by time and intention. Not for profit organization should do a self-assessment to evaluate the companys position because it will help to make continuous growth. References Arvidson, M., Lyon, F. (2014).
