Percentage yield mass of actual yield mass of theoretical yield 100. Mass of product molecular weight of product moles of limiting reagent in reaction stoichiometry of product. If the theoretical yield is 20 g calculate the percentage yield of copper sulfate.
The formula for calculating the percent yield is.
The percent yield is given by the actual yield of a particular reaction product divided by the maximum theoretical yield both in grams multiplied by 100. The molar mass is 2 16 18 gmol. Therefore mass moles x molar mass. So 0725 moles gives 0725 moles of aspirin.
