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 3.00 mL of acetic
anhydride (density = 1.08 g/mL) and 1.25 g of salicylic acid.
Once the reaction is complete, the student collects 1.22 g of aspirin.
Determine the limiting reactant. Determine the theoretical yield of aspirin. Determine the percent yield for the reaction.
