Aspirin (C₉H₈O₄) is produced from salicylic acid (C₇H₆O₃) and acetic anhydride (C₄H₆O₃):

(a) How much salicylic acid is required to produce of aspirin, assuming that all of the salicylic acid is converted to aspirin? (b) How much salicylic acid would be required if only 80% of the salicylic acid is converted to aspirin? (c)What is the theoretical yield of aspirin if 185 kg of salicylic acid is allowed to react with 125 kg of acetic anhydride? (d) If the situation described in part (c) produces 182 kg of aspirin, what is the percentage yield?
