Aspirin is prepared by the reaction of salicylic acid with acetic anhydride as shown in the following equation. The stoichiometry of the reaction is given in the equation. Acetic acid is a by-product of the reaction and must be separated and removed so that aspirin can then be sold as a pure product. How many grams of aspirin can be prepared from 120 grams of salicylic acid? Assume that there is an excess of acetic anhydride.
