Percent Yield Chemistry Example 3

Follow the full solution, then compare it with the other examples linked below.

easy

If the theoretical yield is

25.0

g and the percent yield is

90.0\%

, what is the actual yield?

1
Actual yield $= \text{theoretical yield} \times \frac{\text{percent yield}}{100}$ .
2
Actual yield $= 25.0 \times 0.900 = 22.5\,\text{g}$ .

Answer

22.5\,\text{g}

Rearranging the percent yield formula allows you to predict the actual yield when the efficiency is known.

About Percent Yield

The ratio of the actual yield obtained in an experiment to the theoretical yield predicted by stoichiometry, expressed as a percentage.
