2. In a reaction to make ethyl acetate, 25.5 g CH,COOH react with 11.5 g
CH,OH to give a yield of 17.6 g CH COOCHs.
![The smaller quantity made, 17.0 g NH3, is the theoretical yield so the
limiting reactant is N,.
• The percentage yield is calculated:
16.1 g (actual yield)
17.0 g (theoretical yield)
percentage yield =
x 100 = 94.7%
Verify your result.
The units of the answer are correct. The percentage yield is less than
100%, so the final calculation is probably set up correctly.
PRACTICE
Determine the limiting reactant and the percentage yield for each of
the following.
14.0 g N2 react with 3.15 g H, to give an actual yield of 14.5 g NH3.
In a reaction to make ethyl acetate, 25.5 g CH3COOH react with 11.5 g
CH,OH to give a yield of 17.6 g CH3COOC,H5.
CH3COOH + CH;OH→ CH;COOC,H5 + H2O
