Aspirin (C9H8O4) is synthesized by reacting salicylic acid (C7H6O3) with acetic anhydride (C4H6O3). The balanced equation is given below.
C7H6O3 + C4H6O3 C9H8O4 + HC2H3O2
(a) What mass of acetic anhydride is needed to completely consume 4.40 102 g salicylic acid? What is the maximum mass of aspirin (the theoretical yield) that could be produced in this reaction?
Here is a problem I have posted that gives the basic steps for stoichiometric problems. It isn't the same problem but most of them are worked the same way. Here is the link.
