55. Aspirin, C, H,O, is prepared by reacting salicylic acid, C. H.Os, with acetic anhydride, C. H.03, in the reaction 2CH40,(s) + CHO,(2) = 2C3H4O, s) + HEO(!) A student is cold to prepare 25.0 g of aspirin. He is also cold that he should use a 50.0% excess of acetic anhydride and expect to get a 65.0% yield in the reaction. How many grams of each reactant should he use? please help, thank u!! :))
