Percent Yield Chemistry Example 1

Solution

1. 1
   Start with the percent-yield formula: $\%\text{yield} = \frac{\text{actual yield}}{\text{theoretical yield}} \times 100\%$.
2. 2
   Substitute the given masses: $\%\text{yield} = \frac{42.0}{50.0} \times 100\%$.
3. 3
   Compute the ratio and convert to a percent: $\%\text{yield} = 84.0\%$.
