C
70%
D
75%
Verified step by step guidance1
Understand the concept of percent yield: Percent yield is a measure of the efficiency of a reaction, calculated by comparing the actual yield to the theoretical yield.
Identify the given values: The theoretical yield is 50 grams, and the actual yield is 40 grams.
Use the formula for percent yield: \( \text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100 \% \).
Substitute the given values into the formula: \( \text{Percent Yield} = \left( \frac{40}{50} \right) \times 100 \% \).
Simplify the expression to find the percent yield: Calculate the fraction \( \frac{40}{50} \) and then multiply by 100 to get the percent yield.
