4- Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4) and acetic acid (HC2H3O2). The balanced equation is: C4H6O3 + C7H6O3 → C9H8O4 + HC2H3O2 In a laboratory synthesis, a student begins with 3.00 mL of acetic anhydride (density = 1.08 g/mL) and 1.25 g salicylic acid. Once the reaction is complete, the student collects 1.22 grams of aspirin.Determine the limiting reactant, theoretical yield of aspirin, and...
