Question

Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3C4H6O3) with salicylic acid (C7H6O3C7H6O3) to form aspirin (C9H8O4C9H8O4) and acetic acid (C2H4O2C2H4O2). The balanced equation is
C4H6O3+C7H6O3→C9H8O4+C2H4O2C4H6O3+C7H6O3→C9H8O4+C2H4O2
In a laboratory synthesis, a student begins with 2.90 mLmL of acetic anhydride (density=1.08gml−1density=1.08gml−1) and 1.28 gg of salicylic acid. Once the reaction is complete, the student collects 1.20 gg of aspirin.
