Aspirin is prepared from the reaction of salicylic acid (C7H6O3) andacetic anhydride(C4H6O3) to produce aspirin (C9H8O4) andacetic acid(HC2H3O2). The formula for this reaction is
C7H6O3+ C4H6O3→ C9H8O4+ HC2H3O2.
How many grams of salicylic acid are needed to make 1000 1-gram tablets of aspirin? (Assume 100% yield)
