The percent yield is based upon the theoretical yield. Write a balanced equation for the reaction 2. 32 req limiting reagent x 3 stoichiometric factor x 123 mgmmol MW of product 11808 mg 118 g expected yield.
32 req limiting reagent x 3 stoichiometric factor x 123 mgmmol MW of product 11808 mg 118 g expected yield.
To determine the theoretical yield multiply the mass of acetaminophen reported as 0157g by the molar mass of acetaminophen. Theoretical yield H 2 O 150 mol H 2 x 2 mol H 2 O 2 mol H 2. Now that we know the theoretical yield of the problem we can now plug all the numbers in the original formula actual yield theoretical yield x 100 to calculate percentage yield. It shows you how to determine the percent error using a formula.
