Aspirin, C\9H\8O\4, is prepared by reacting salicyclic acidC\7H\6O\3, with acetic anhydride, C\4H\6O\3, in the reaction
C\7H\6O\3(s) + C\4H\6O\3 ---> C\9H\8O\4(s) + C\2H\4O\2(l)

A student is told to prepare 45.0 g of aspirin. She is also told touse a 55.0% excess of acetic anhydride and to expect to get an 85%yield in the reaction. How many grams of each reactant should sheuse?
