Aspirin (C9H8O4) may be synthesized by mixing salicylic acid (C7H6O3) with excess acetic anhydride (C4H6O3). When 2.0 g of salicylic acid is mixed with excess acetic anhydride, 1.7 g of aspirin is collected. What is the percent yield of this reaction? The balanced equation is C7H6O3 + C4H6O3 C9H8O4 + C2H4O2 A.98 % B.85 % C.77 % D.65 % E.55 %

Expert Solution
Step 1
Given mass of salicylic acid = 2.0 gram
Molar mass of salicylic acid = 138.12 g/mol
Moles of salicylic acid = 2/138.12 = 0.0145 moles
