Question

If 3.48 g of copper are recovered at the end of this experiment after allowing 4.00 g of copper to react with nitric acid in reaction #1, what is the theoretical yield and the actual percent yield of the reaction?

Answer 1

Answer : The theoretical yield and actual yield of the reaction are 4.00 g and 3.48 g respectively.

Explanation :

Theoretical yield : It is calculated from the amount of the limiting reagent present in the reaction.

Actual yield : It is experimentally determined. That means the amount obtained at the end of the experiment.

From this we conclude that, 3.48 g is the actual yield of the reaction because this amount is obtained at the end of the experiment and 4.00 g is the theoretical yield of the reaction because this amount is used in the calculation that means it is a calculated amount.

Hence, the theoretical yield and actual yield of the reaction are 4.00 g and 3.48 g respectively.

Answer 2

The theoretical yield is = 4.00 g; this is because it was the original mass of copper that had to be recovered.

The percentage yield = 87.0%

calculation

% yield = actual yield/theoretical yield x 100

actual yield = 3.48

5 yield is therefore= 3.48/4.00 x100= 87.0 %
