Understand that percent yield is a measure of the efficiency of a chemical reaction, comparing the actual yield to the theoretical yield.
Recall the formula for percent yield: \(\text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100\%\).
Identify the given values: Theoretical yield = 50 g, Actual yield = 40 g.
Substitute the given values into the formula: \(\text{Percent Yield} = \left( \frac{40}{50} \right) \times 100\%\).
Simplify the fraction and multiply by 100 to find the percent yield (do not calculate the final number here).
