Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9 H8O4) and acetic acid (C₂H4O₂). The balanced equation is C4H6O3 + C7H6O3 → C9H8O4 + C₂H4O2 In a laboratory synthesis, a student begins with 5.96 mL of acetic anhydride (density = 1.08 g/ml) and 2.23 g of salicylic acid. Once the reaction is complete, the student collects 1.76 g of aspirin. Determine the limiting reactant for the reaction.
