Determine the limiting, excess reagent & percent yield of the reaction.

Aspirin (acetylsalicylic acid, C₉H₈O₄) can be made by reacting salicylic acid (C₇H₆O₃) with acetic anhydride [(CH₃CO)₂O] by the following reaction:

C₇H₆O_{3 (}s₎ + (CH₃CO)₂O₍l₎ → C₉H₈O_{4 (}s₎ + CH₃COOH₍l₎

In one reaction, 7.947g of salicylic acid and 12.65mL of acetic anhydride react to form 5.961g of aspirin.

a. What is the limiting reagent? (The density of acetic anhydride is 1.080g/mL)

b. How much excess reagent is left after the reaction reaches completion?

c. What is the percent yield of this reaction?
