QUESTIONS 1. Calculate the number of grams of salicylic acid needed to produce 225 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 128.0 grams, what would be the percentage yield for the reaction if 78.0 grams of acetaminophen were recovered in the final step of the reaction and isolation process? 3. In that last synthesis step for acetaminophen (CHNO 151.16 g/mol), a compound called 4- aminophenol (C.H-NO; 109.13 g/mol) is reacted with acetic anhydride. Calculate the theoretical yield of acetaminophen that could be produced from 35.0 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. 8
