What is the percent yield for a reaction if the theoretical yield of c6h12 is 21g and the actual yield recovered is only 3.8g?

The percent yield can be calculated using the formula: (\text{Percent Yield} = \left(\frac{\text{Actual Yield}}{\text{Theoretical Yield}}\right) \times 100). Substituting the given values: (\text{Percent Yield} = \left(\frac{3.8 , \text{g}}{21 , \text{g}}\right) \times 100 \approx 18.1%). Therefore, the percent yield for the reaction is approximately 18.1%.
