Final answer:
The percent yield for the reaction, given an actual yield of 71.71 g of soap and a theoretical yield of 83.71 g, is 85.67%.
Step-by-step explanation:
The student's question pertains to calculating the percent yield of a chemical reaction. To find the percent yield, the student must compare the actual yield, which is the measured amount of product obtained from the reaction, to the theoretical yield, which is the calculated maximum amount of product that could be formed based on stoichiometry.
The formula for percent yield is: (actual yield / theoretical yield) x 100%. Using the given data, the calculated percent yield is (71.71 g / 83.71 g) x 100% = 85.67%, rounded to the hundredths place.
