Answer
130 g
Work Step by Step
Calculating how much product can be made based on the amount of each reactant, we have:
$100\,g\times\frac{1\,mol\,salicylic\,acid}{138.121\,g}\,\times\frac{2\,mol\,aspirin}{2\,mol\,salicylic\,acid}=0.724\,mol\,aspirin$
$100\,g\times\frac{1\,mol\,acetic\,anhydride}{102.09\,g}\times\frac{2\,mol\,aspirin}{1\,mol\,acetic \,anhydride}=1.96\,mol\,aspirin$
Since salicylic acid makes the least amount of product, it is the limiting reactant.
Therefore, the maximum mass of aspirin that can be obtained=
$0.724\,mol\,aspirin\times\frac{180.158\,g}{1\,mol\,aspirin}=130\,g$
