Be sure to answer all parts.

Aspirin or acetyl salicylic acid is synthesized by reacting salicylic acid with acetic anhydride:

C7H6O3          + C4H6O3                → C9H8O4  +  C2H4O2

salicylic acid    acetic anhydride        aspirin        acetic acid

(a) How much salicylic acid is required to produce 0.450 g of aspirin, assuming acetic anhydride is  present in excess?

(b) Calculate the amount of salicylic acid needed if only 72.8 percent of salicylic acid is converted to aspirin.
