4-aminobenzoic acid
137.14 g/mol
Benzocaine
165.19 g/mol
A student starts with 0.345 g of pure 4-aminobenzoic acid, (molar mass 137.14 g/mol) and ends up with 0.345 g benzocaine
(molar mass 165.19 g/mol).
Given that ethanol is in excess, what are the theoretical and percent yields for this reaction? Assume all starting material is
converted to product when calculating the theoretical yield.

theoretical yield:
%
percent yield:
