OK, basic chem question.
Aspirin is prepared by the reaction of salicylic acid(C7H6O3) with acetic anhydride(C4H6O3) according to the following equation:
C7H6O3 + C4H6O3 ----> C9H8O4 + CH3CO2H
How many grams of acetic anhydride are needed to react with 4.50 grams of salicylic acid? How many grams of aspirin are formed? How many grams of acetic acid are formed as a by-product?
I found the weight of acetic anhydride(3.32 grams) but I cannot for the life of me figure out how to find the weights of the aspirin and the acetic acid. Any help?
