Percent yield is the percent ratio of actual yield to the theoretical yield. You can begin with either product to calculate theoretical yield. The theoretical yield of 100 g is the calculated amount of product assuming that the reaction is 100 efficient The percentage yield is the ratio of actual yield to theoretical yield expressed as a percentage.
You determine percent yield of a chemical reaction with the following formula.
Percent yield is a formula used by chemists in the process of evaluating chemical reactions. When calculated the actual yield reveals the true amount of product produced by the reaction. 37 g100 g 100 37 3. Calculating Percent Yield 1.
