QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...

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.
