Answer :
We may calculate the moles of silver that should have been generated given the amount of copper.
For these issues, we must contrast the theoretical yield that would result from using stylometric with the given theoretical yield. % Yield is actual yield/theoretical yield multiplied by 100% Cu + 2 Ag. Two moles of silver are produced for every mole of copper when NO is present. 12.7 g Cu times 1 mol Cu times 63.5 g Cu times 2 mol Ag times 108 g Ag times 1 mol Ag is 43.2 g Ag. The theoretical yield is as follows. Now that we get 38.1 g of Ag, our yield is 38.1 g/43.2 g x 100%, which equals 88.2%. Since we know from the reaction's stylometric that 1 mol of copper generates 2 moles of silver.
