Aspirin can be made by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4). C4H6O3 + C7H6O3 --> C2H4O2 + C9H8O4 When synthesizing aspirin, a student began with 3.05 mL of acetic anhydride (density = 1.08 g/mL) and 1.85 g of salicylic acid. The reaction was allowed to run its course and 1.84 grams of aspirin was collected by the student. Determine the limiting reactant, theoretical yield of aspirin, and percent yield for the reaction.
