Aspirin, C9H8O4, is prepared by reacting salicylic acid, C7H6O3, with
acetic anhydride C4H6O3, in the reaction
C7H6O3(s) + C4H6O3(l) ( C9H8O4 + C2H4O2(l)
A student is told to prepare 45.0g of aspirin. She is also tole to use
55.0%exess of acetic anhydride and to expect to get an 85% yield in the
reaction. How many grams of each reactant should she use?
