Readings
Theoretical yield and percent yield
To compute the percent yield, it is first necessary to determine how much of the product should be formed based on stoichiometry. This is called the theoretical yield, the maximum amount of product that could be formed from the given amounts of reactants. The actual yield is the amount of product that is actually formed when the reaction is carried out in the laboratory. The percent yield is the ratio of the actual yield to the theoretical yield, expressed as a percentage.
The percent error is the absolute value of the error divided by the accepted value and multiplied by 100%. Use this reading to learn how to calculate percent error.

Theoretical yield and percent yield
This video shows you how to calculate the theoretical and percent yield in chemistry. The theoretical yield is the maximum amount of product that can be produced in a reaction. The percent yield is equal to the actual yield divided by the theoretical yield times 100%.
