This will be compared to theexperimental mass you obtained, by calculating the percent yield. Percent yield = (experimentalmass of soap/theoretical mass of soap)x100.4A. Divide the mass of Crisco used by the molecular weight (MW) of fat in Crisco. The answeris the number of moles of fat used.4B. Multiply the number of moles of fat used, by three. The answer is the number of moles ofsoap theoretically obtainable. (Remember that one mole of fat yields three moles of soap.)4C. Multiply the theoretical number of moles of soap obtainable, by the MW of soap. Theanswer is the theoretical mass of soap obtainable.4D.Divide the experimental mass of soap you obtained, by the theoretical mass of soapobtainable, and multiply the answer by 100. The answer is the percent yield of soap.
