WebCalculate the percentage yield by using the values of the actual yield that is provided in the question and the theoretical yield that you calculated in step 5. Amount of Substance – Calculating Percentage Yields. Percentage yield = (actual yield ÷ theoretical yield) x 100= (9.6 ÷ 11.6) x 100= 82.8%. →What is the amount of substance in ... WebWhen performing reacting mass calculations, the limiting reagent is always the number that should be used, as it indicates the maximum possible amount of product that can form. Once all of a limiting reagent has been used up, the reaction cannot continue. The steps are: Convert the mass of each reactant into moles by dividing by the molar masses.
