Question

in a chemical reaction, if the actual yield is 75 grams and the theoretical yield is 80 grams, what is the percent yield?
a. 93.75%
b. 75%
c. 50%
d. 120%

Explanation:

Step1: Recall percent - yield formula

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

Step2: Substitute given values

Percent yield = $\frac{75}{80}\times100\%$

Step3: Calculate the result

$\frac{75}{80}\times100\% = 0.9375\times100\%=93.75\%$

Answer:

A. 93.75%
