What is the percent yield if 95.125 g of Aspirin is recovered

Question

C₇H₆O₃ + C₄H₆O₃  C₉H₈O₄ + C₂H₄O₂

Acetic acid is a byproduct of the reaction.

Aspirin is synthesized in a reaction with a theoretical yield of 0.330 moles of aspirin.

Answer 1

If the theoretical yield in the particular experiment is 0.330 moles of aspirin (as indicated in the question), we can find the % yield by comparing the actual yield of 95.125 g to the theoretical yield, after converting the 0.330 moles to grams.

0.330 moles aspirin x 180.158 g/mole = 59.461 g = theoretical yield

NOTE: This turns out to be LESS than the actual yield which is not possible. It would be interesting to see where you obtained the value of 0.330 moles as the theoretical yield.
