Aspirin can be prepared from salicylic acid (C7H6O3C7H6O3), which has a molar mass of 138.12 g/mol, and acetic anhydride (C4H6O3C4H6O3), which has a molar mass of 102.04 g/mol. The density of acetic anhydride is 1.082 g/mL. C7H6O3+C4H6O3⟶C9H8O4+C2H3O2C7H6O3+C4H6O3⟶C9H8O4+C2H3O2 What is the yield of aspirin (C9H8O4C9H8O4), which has a molar mass of 180.15 g/mol, possible when reacting 2.02 g of salicylic acid with 1.07 mL of acetic anhydride?
