Aspirin (C9H8O4) is produced by the reaction of salicylic acid (M = 138.1 g/mol) and acetic anhydride (M = 102.1 g/mol).
C7H6O3(s) + C4H6O3(l) ? C9H8O4(s) + C2H4O2(l)
If 35.0 g of C7H6O3 are reacted with 20.6 g of C4H6O3, answer the following questions:
(i) What is the limiting reagent?
(ii) What is the theoretical yield of aspirin (C9H8O4)?
(iii) What is the theoretical yield of C2H4O2?
(iv) If only 28.8 g of aspirin are produced, what is the percent yield of the reaction?
(v) How much unreacted material remains after the reaction?
