Aspirin (C₉H₈O₄) is produced from salicylic acid (C₇H₆O₃), and acetic anhydride (C₄H₆O₃), as shown below.

C₇H₆O₃ + C₄H₆O₃ → C₉H₈O₄ + HC₂H₃O₂

(a) How much salicylic acid is required to produce 1.0  10² kg of aspirin, assuming that all of the salicylic acid is converted to aspirin?

(b) How much salicylic acid would be required if only 56% of the salicylic acid is converted to aspirin?

(c) What is the theoretical yield of aspirin if 181 kg of salicylic acid is allowed to react with 124 kg of acetic anhydride?
