Stoichiometry Southeast Missouri State University
Percent Mass of Copper in a Penny Introduction The purpose of this lab is to determine the percent mass of Cu in a penny and see if the fabricator that makes the planchets for the government is using the correct amounts of Cu in the pennies.... Question: Calculate the theoretical mass percent of copper for the compound obtained in part III calculate the theoretical mass percent of copper for the compound obtained in part III Expert Answer

Video-Given the chemical formula of a hydrate find the

mass of copper that we started with. We will calculate the percent recovery of copper and see how well we did. Notice that we are not calling this percent yield because the product is the same as the main reactant. The first reaction is an oxidation-reduction reaction shown in equation 1. (1) Cu (s) + 4 H 3O + (aq) + 2 NO 3 - (aq) [Cu(H 2O) 6] 2+ (aq) + 2 NO 2 (g) This reaction actually occurs...
Determine the mass of Cu dissolved in the brass solution based upon the molarity. Calculate the percent of copper in the brass sample. Find another group who used the same brass.

Calculate the percentage mass of copper in the ore sample
After more thought, we came to the conclusion that the final amount of copper that was weighed to calculate the final mass contains impurities introduced by the reactions in the lab, and these impurities altered the mass of the final product. In the final reaction, solid zinc was added to aqueous copper sulfate. If there was any solid zinc that did not react with the copper sulfate and was how to get free trial prime Determine a percent yield for the mass of recovered copper. The actual yield is the The actual yield is the amount you ended up with, the theoretical yield can be found from the limiting. How to find the best university for you

## How To Find Theoretical Percent Mass Of Copper In Cu2co5h2

### In the old days the pennies were mostly copper, but as the price of copper metal increased there was more than a pennies worth of copper in a penny. So the US mint switched to a Zn core which is copper clad. More trivia is that in 1943 pennies were steel with a Zn coating. Pennies in 1944 were odd too because they were made from brass gun shell cases.

• A mass of 2.00g of Copper (11) dihydrate salt to 0.01 g was dissolved in 50.0ml of water in a beaker The Aluminum was folded length wise to make a strip 1 cm x 15 cm. The strip was coiled loosely to fit into a Copper Chloride solution in a beaker, making sure that the strip is entirely immersed.
