Interpretation: The actual yield is to be calculated
Concept introduction: After the completion of reaction the amount of product formed is known as yield. The theoretical yield is the calculated amount of yield that is obtained when the reaction gets completed. The percent yield is the ratio of obtained yield by theoretical yield.

Answer to Problem 62A
The actual yield is 5 g .
Explanation of Solution
Given information: The percent yield is 40.0 % . The theoretical yield is 12.5 g .
The formula to calculate percent yield is,
%yield=Actual yieldTheoretical yield×100
Substitute the value of theoretical yield and percent yield in the above formula.
%yield=Actual yieldTheoretical yield×10040.0=Actual yield12.5 g×100Actual yield=40.0×12.5 g100=5 g
The actual yield is 5 g .
