Percentage yield mass of actual yield mass of theoretical yield 100 Lets assume that you obtained an actual yield of 850 grams. The theoretical yield is a term used in chemistry to describe the maximum amount of product that you expect a chemical reaction could create. The actual mass obtained is 1212 g.
Find the theoretical yield.
We must use the equation below. The percent yield is the ratio of the actual yield to the theoretical yield expressed as a percentage. Finding Theoretical and Percent Yield. We must use the equation below.
