when 1.00kg of copper reacts, 3.12kg of silver is recovered. what is the percentage yield?
Cu + 2Ag^+ ==> 2Ag + Cu2+
mols Cu = grams/stomic mass = approx 15 but you need a more accurate answer than that estimate.
Now convert mols Cu to mols Ag expected. That's approx 15 g Cu x (2 mols Ag/1 mol Cu) = approx 30 mols. How much Ag is that in grams?
That's 30 g Ag x atomic mass Ag = approx 3400 or approx 3.4 kg Ag. That's the theoretical yield (TY). The actual yield (AY) in the problem is 3.12 kg.
%yield = (AY/TY)*100 = ?
