'Molar Mass of Oxygen Essay\r'

'Applying the individual % of elements in peeing to the hoagie wad\r\nConclusion____________________________________________________________\r\nIn conclusion the experimental grade of the groynear good deal of oxygen is. To achieve this result, we wrote the chemical reaction, compared the symmetry of mole between and, find the mole produced by peeing use the formula, calculate the molar spate from the mol rank, calculate the % of individual elements in water, and determination oxygen’s molar mass from the boilersuit molar mass.\r\nAnalysis & Evaluation ___________________________________________________\r\n-In analysis, our results hand over an unreasonable result. The majority of the failure is from the masses result. From Avogrado’s law we know that. As such, because the average intensiveness (0.051 L) was low, the mol resulting from it is also low. A small mol results in a large Mr value, or in our case the Mr of atomic number 8 is too high.\r\n-An other point to that is that if the experiment was assuming r.t.p, our results prove to be incorrect again. If we compared the mol, the literal mol results of andusing the ideal splosh laws is different than if we figure using normal Stoichiometry.\r\nFrom Stoichiometry, the actual mol of is, and if we compared it to a ratio of 2:2, the actual mol value of is also 0.138 mol. However in our experiment using the gas law, our mol result was. Again this is cod to the fact of the low amount of volume recorded.\r\n-In appurtenance to that point, from the section to: Calculate molar mass of Water using the mass of Hydrogen Peroxide , other flaw to the experiment was the amount of uncertainty in the result. From the section we apply the ‘law of conservation of mass’ stating that no mass is created or destroyed. Or in this experiment’s case, most of the mass decomposes into Oxygen gas and finally results in the volume of water displaced from the process.\r\nHowever a s shown from the low amount of volume our group collected, this can result in deuce conclusions.\r\nThe first conclusion is that most of the oxygen gas that eventually turns into the volume of water left is baffled to the surroundings (from the test underground openings) OR the min conclusion is that our group did not wait yen enough and thus lost some emf volume results.\r\n-To evaluate, the major flaw to the experiment was the value of the data collected.\r\nPart of the reason was because we used Vaseline as a tool to reduce the amount of vital force (in the form of the Oxygen gas) to the surroundings.\r\nVaseline is a good legal profession to do so, however a better resource is probably to increase the number of trials, to have a more close system that may significantly reduce the uncertainties, and to maybe reduce the length of arctic tube (by reducing the length of rubber tube the amount of water left is reduced).\r\nReferences\r\nIB- Foundation books.\r\nRaymond Chan g (pg: 87, 181, 182, 191.etc)\r\n'
