Determine themass of the copper solid produced when excess magnessuim metal reacts with 250 ml of 0.0500M copper acetate solution. if 6.00g of copper was recovered experimentally determine the percent yeild.

Question

Determine themass of the copper solid produced when excess magnessuim metal reacts with 250 ml of 0.0500M copper acetate solution. if 6.00g of copper was recovered experimentally determine the percent yeild.

Thank you in advance.

Answer 1

Mg + Cu(Ac)2 ==> Mg(Ac)2 + Cu

mols Cu(Ac)2 = M x L = ?
Using the coefficients in the balanced equation, convert mols Cu to mols Mg.
Now convert mols Mg to g Mg. g = mols x molar mass. This is the theoretical yield (TY). The actual yield (AY) is 6.00g
% yield = (AY/TY)*100 = ?
