Yield

Yield of CuCl2.2DMSO Formula weight (Mr) of CuCl2 = 63.55 + (35.45 x 2) =134.45g/mol Formula weight of product CuCl2.2DMSO = 134.45 + 2[16 + 32.06 + (12.01 x 2) + (1.0079 x 6)] = 290.704g/mol Mass of CuCl2= 0.850g Equation for reaction CuCl2 + 2DMSO -> CuCl22DMSO Mole ratio between CuCl2 and CuCl22DMSO = 1:1 Mole of CuCl2 = Mass/ Mr = 0.850/134.45 = 0.00632 moles Since the ratio between CuCl2 and CuCl22DMSO = 1:1, mole of CuCl2DMSO is also 0.0063 moles. To find theoretical yield of...

Explaining Yield Curves

The Yield Curve is very similar to the term structure except that it is based on coupon bond yields whereas the term structure is based on only pure discount bonds. In looking at the current Yield Curve we can see that the general shape is that of an upward-sloping structure. In relation to anticipated future inflation this curve indicates that inflation is expected increase which is evident by the increasing size of the inflation premium wedge that is causing the overall curve to slope upward...

Preparation of an Ionic Compound from Aluminum Metal

following formula: KAl(SO4)2(aq) xH20 After the formula of the product had been deduced, it was then possible to complete the third and final objective of the project, which was to calculate the theoretical yield, the actual yield, and then the percentage yield of the preparation. These yields were surmised by using specific stoichiometric calculations. Experimental Method To form alum, 0.50 g of aluminum powder (Al(s)) were added to 2.01 g of Potassium Hydroxide (KOH(aq)) in a 400 mL beaker....

Lab Experiment Stoichiometry of a Precipitation Reaction

The purpose of this experiment is to use stoichiometry to predict how much of a product will be made in a precipitation reaction, to measure the reactants and products of the reaction correctly, to figure out the actual yield vs. the theoretical yield and to calculate the percent yield.   Procedure First, 1.0 g of CaCl2·2H2O was put into a 100-mL beaker and 25 mL of distilled water was added. The two ingredients were stirred to create a calcium chloride solution. Then, stoichiometry was used to...

Stoichiometry Lab

Copper(II) oxide will be synthesized from a known mass of copper(II) sulfate pentahydrate. Using the relationship of the balanced equation, and other stoichiometry relationships, you will calculate a theoretical yield of CuO, and your actual yield. You then will calculate a percent yield. Copper(II) sulfate pentahydrate will be dissolved in water and reacted using a double replacement reaction with sodium hydroxide. The addition of hydroxide ions to a solution containing copper(II) ions results...

Tensile Strength Report

samples from each plastic material type, we are able to obtain the mean tensile strength, mean tensile modulus and mean yield strength of each material. With this, the results is that PP is the most elastic among them, but the strongest material seems to be GPPS as it has the highest mean tensile strength and mean tensile modulus among the four different plastics. But GPPS did not yield at all as it does not have any crosslinks to favour elastic properties. Content Page * Introduction * Theory ...

Lab 1 Nitration Of Naphthalene

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion, which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product, and the melting point of the possible results were 59 °C for 1-nitronaphthalene, and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated...

procedure, the calculation included will be the percent yield). Present a data table containing all of the other data related to the procedure that was not found in the example calculation. Present a statement of final results from the procedure along with its reliability (i.e., average plus percent deviation). Section 2.0 will not have this statement since the only result is the grams of your unknown which is included in the percent yield calculation. Conclusions (5 pts) In between the end of...
