Example of Molar Mass Calculation

You can calculate the molar mass or the mass of one mole of an element or molecule if you know the formula for the substance and have a periodic table or table of atomic masses. Here are some worked examples of the molar mass calculation. How to Calculate Molar Mass The molar mass is the mass of one mole of a sample. To find the molar mass, add the atomic masses (atomic weights) of all of the atoms in the molecule. Find the atomic mass for each element by using the mass given in the Periodic Table or table of atomic weights. Multiply the subscript (number of atoms) times the atomic mass of that element and add the masses of all of the elements in the molecule to get the molecular mass. Molar mass usually is expressed in grams (g) or kilograms (kg). Molar Mass of an Element The molar mass of sodium metal is the mass of one mole of Na. You can look up that answer from the table: 22.99 g. You may be wondering why the molar mass of sodium isnt just twice its atomic number, the sum of the protons and neutrons in the atom, which would be 22. This is because the atomic weights given in the periodic table are an average of the weights of the isotopes of an element. Basically, the number of protons and neutrons in an element may not be the same. The molar mass of oxygen is the mass of one mole of oxygen. Oxygen forms a divalent molecule, so this is the mass of one mole of O2. When you look up the atomic weight of oxygen, you find it is 16.00 g. Therefore, the molar mass of oxygen is: 2 x 16.00 g 32.00 g Molar Mass of a Molecule Apply the same principles to calculate the molar mass of a molecule. The molar mass of water is the mass of one mole of H2O. Add together the atomic masses of all of the atoms of hydrogen and water in a molecule of water: 2 x 1.008 g (hydrogen) 1 x 16.00 g (oxygen) 18.02 g For more practice, download or print these molar mass worksheets: Formula or Molar Mass Worksheet (pdf)Formula or Molas Mass Worksheet Answers (pdf)

Poverty, By John Kenneth Galbraith - 1775 Words

Poverty is a huge issue which never seems to ever go away or be fixed. There are many options as to what can be done to eliminate poverty but, not all options please everyone. John Kenneth Galbraith in his essay â€Å"The Position of Poverty† argues that â€Å"to eliminate poverty, we must invest more than proportionately in the children of the poor community (Jacobus). Money has been a very important tool that has divided the world and given humans labels as wealthy or poor. The wealthy seem to have worked hard for what they have but others not so much. Poverty has been growing and it has been spreading across the world. Those people who are poor sometimes have no chance to exit the poverty that have been in because of very little supplies or just not a great community or environment, some with very little food and they just give up and never keep trying to exit this moment in their lives. The rich must make an effort to try and redistribute the money in our nation to elimi nate poverty for good. There has always been a gap between the incomes of all people. Since the 1920’s we haven’t had that much of gap up until now of course. America has more wealth and more income inequality than any other major developed country on earth, and the gap between the very rich and everyone else is wider than it has been at any time since the 1920s (Sanders). If we think about that clearly and critically we find out that something is seriously wrong.

IT Priorities IVK for Effective Project Management- myassignmenthelp

Question: Discuss about theIT Priorities IVK for Effective Project Management. Answer: Slush fund slack had been created by the previous CIO Davies just in case when the very vital projects at IVK could not be approved. The slush funds had been developed at IVK in order to get the IT project funds approved. The IT projects were not considered to be the primary functions rather they were just the supporting functions which faced trouble to get budgetary approvals from the department. To get budget approval for the IT projects that were very technical and did not deliver direct customer benefits were really tough to get approved in IVK. Moreover the IT projects were supposed to be very technical and the other departments were simply unable to understand, rather in some cases the approach that the company IVK adopted for funding the IT projects was that of preventive maintenance. This is the reason why Davies created slush funds to get these security related risks handled effectively (Wysocki, 2010). Davies being a technical person knew very well the kind of security risks might generate if the IT projects do not get implemented. He realised the importance and gravity of neglecting of IT projects in IVK that is why he thought of this idea of creating slush fund slack to get budgetary approval for the IT projects. During the IT project approval in which Barton made fun when he started criticising the way the project was presented Davies simply returned back in his shell during conflicts. This indicates that Davies, not being the one ready to take sole responsibility, will result in noose around everyones neck as everyone would get involved while decision making for the IT projects (Austin, Nolan, O'Donnell, 2016). The approach adopted by Davies was typically IT-based approach and not a management based approach. The approach adopted by Davies was technology oriented as he along with John both believed that there exists a security issue with the technology that was being used by Peoples. He believed that if there is any security risk that must be handled by receiving funds from IVK. But his approach being too much IT related which was simply did not go very well with other business units. He laid more emphasis on the security risks that might arise in totally IT language. Thus the way of communication of the security risks adopted by Davies did not clarify or show what adverse impact the security risks that are generated in IVK can have on the company as well as the customers. Thus the approach adopted by Barton that the IT spending needs to be in proper alignment with the IVK strategy and dividing the IT projects on the following basis is a better approach. The projects will be divided into categories like: Mandatory (for example security) Return on Investment (for example incremental) OCI (option creating investment). Barton has adopted a consensus approach according to which IT is important aspect that assists the process implementation and the business units are the ones who decide the priorities. The approach followed by Barton does not suggest that it should take full control over the IT budget rather it believes in putting forth the IT point of view along with the business point of view. By adopting this approach all necks will be in the noose and in case any decision goes wrong everyone who is part of decision can be blamed and held responsible (Austin, Nolan, O'Donnell, 2016). Barton needs to act smart and should not take the entire budgetary control in his hands as suggested by Maggie as well as it will make him responsible for anything that goes wrong in the company. He should come up with a brilliant idea of getting fixed the whole decision making committee which should also engage the Board of Directors. Rather he should try to create a completely new IT budgeting process by proposing certain percentage of the total budget that needs to be allocated to the IT projects that belong to the mandatory category (Wysocki, 2010). The IT committee that he needs to propose should be of board level because demanding certain percentage of budget to be taken into control of IT is not a good idea. In this case again if anything goes wrong then only Barton will be held responsible because the noose would be around his neck only, being the sole person to make budgetary decisions. What he needs to do is support the formation of an IT Security Project which should empha size on the critical factors as well as the benefits that it will draw. IT Committee with board involvement will help in promoting the say of IT within the business units which will in turn help the organization also. Thus the risks associated with IT infrastructure will be decreased and will also make decision making simple and easy (Austin, Nolan, O'Donnell, 2016).
