This video shows you how to calculate the theoretical and percent yield in chemistry. Calculating Percent Yield 1. The percent yield of this reaction is going to be the actual yield divided by the theoretical yield multiplied by 100.
Multiply the value you get by 100 in order to get the value of the actual yield.
Calculating the percent yield helps you to know the effectiveness of your performed reaction. Click the little calculator symbol in the top right corner to open the calculator. Usually you have to calculate the theoretical yield. The percentage yield is calculated using this equation.
