If the theoretical yield of a reaction is 80.0 g and the percent yield is 95%, what is the actual yield?

• A. 84.2 g
• B. 8.4 g
• C. 95.0 g
• D. 76.0 g

Answer: (D)

Verified step by step guidance

1. Understand the relationship between theoretical yield, actual yield, and percent yield. The percent yield is given by the formula: \(\text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100\%\).
2. Rearrange the formula to solve for the actual yield: \(\text{Actual Yield} = \frac{\text{Percent Yield} \times \text{Theoretical Yield}}{100\%}\).
3. Substitute the given values into the formula: percent yield = 95%, theoretical yield = 80.0 g.
4. Calculate the actual yield by multiplying 95% (expressed as 95) by 80.0 g, then divide by 100 to convert the percent to a decimal.
5. Interpret the result as the actual amount of product obtained from the reaction, which should be less than or equal to the theoretical yield.
