Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2) . The balanced equation is: C4H6O3+C7H6O3→C9H8O4+C2H4O2 .In a laboratory synthesis, a student begins with 5.00 mL of acetic anhydride (density = 1.08 g / mL ) and 2.08 g of salicylic acid. Once the reaction is complete, the student collects 2.09 g of aspirin. Determine the percent yield for the reaction.
