1. Calculate the number of grams of salicylic acid needed to produce 125 grams of aspirin, assuming the
reaction will be 100% efficient. Show your work using dimensional analysis.
2.
If the theoretical yield for the synthesis of the pain reliever acetaminophen in a reaction was 118.0
grams, what would be the percentage yield for the reaction if 89.0 grams of acetaminophen were
recovered in the final step of the reaction and isolation process?
3.
In that last synthesis step for acetaminophen (CsHNO2; 151.16 g/mol), a compound called 4-
aminophenol (C. HNO; 109.13 g/mol) is reacted with acetic anhydride. Calculate the theoretical yield
of acetaminophen that could be produced from 25.0 grams of 4-aminophenol reacting with an excess of
acetic anhydride if one mole of acetaminophen is produced from one mole of 4-aminophenol. Show
your work using dimensional analysis.
