Percent Yield Formula

What is Percent Yield?

The ratio of actual yield to the theoretical yield when multiplied by 100 is called Percent Yield. It is important in chemistry used to analyze the percentage of conversion of reactant into product. The theoretical yield is calculated using the stoichiometric equation used to represent the chemical reaction. The actual yield is measured in the lab after the reaction has been completed. It should be noted that the units of actual yield and theoretical yield should be the same. The generally preferred units are mole or gram to express actual yield and theoretical yield....

Theoretical Yield

The maximum amount of product that is produced in a chemical reaction is called the Theoretical Yield. Theoretical Yield is the yield of the product based on the theoretical chemical reaction under ideal conditions. In general, the theoretical yield is never achieved in the actual reaction or in the lab due to the presence of impurities and other hindrances from the surrounding....
