Aspirin can be made in the laboratory by reacting acetic anhydride (C4HO3) 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 3.10 mL of acetic anhydride (density=1.06 g/ml) and 1.23 g of salicylic acid. Once the reaction is complete, the student collects 1.23g of aspirin.
Determine the theoretical yield and percent yield of aspirin.
