Question

1. in a chemical reaction, the actual yield is 90 grams, and the theoretical yield is 100 grams. what is the percent yield? a. 90% b. 10% c. 110% d. 80%

Explanation:

Step1: Recall percent - yield formula

Percent yield = $\frac{\text{Actual Yield}}{\text{Theoretical Yield}}\times100\%$

Step2: Substitute given values

Percent yield = $\frac{90}{100}\times100\%$
Percent yield = $90\%$

Answer:

A. 90%
