Question
Aspirin can be synthesized in the lab by combining salicylic acid (C7H6O3) and acetic anhydride (C4H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2) The balanced equation for this reaction is
C7H6O3+C4H6O3⟶C9H8O4+C2H4O2
A student started with 3.56 mL of acetic anhydride (density=1.08 g/mL) and 2.28 g salicylic acid. The student synthesized 2.40 g of aspirin.
a) Select the limiting reactant.
salicylic acid (C7H6O3)
acetic acid (C2H4O2)
aspirin (C9H8O4)
acetic anhydride (C4H6O3)
b) Calculate the theoretical yield of aspirin (C9H8O4).
c) Calculate the percent yield for aspirin (C9H8O4).
