Calculating Percent Yield 1. So ideally 336 grams of CaO should have been produced in this reaction. List the known quantities and plan the problem.
Percent recovery computes the percentage of an original substance that is recovered after a chemical reaction is completed.
Percent Yield Step 1. The theoretical yield you calculated assumes that everything went perfectly. The percent yield of this reaction is going to be the actual yield divided by the theoretical yield multiplied by 100. Theoretical yield Actual yield100.
