question 15 of 30
the theoretical yield of ammonia in a reaction is 865 g. what is the percent yield if 657 g is produced?
a. 152%
b. 76.0%
c. 38.0%
d. 132%

Explanation:

Step1: Recall percent - yield formula

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

Step2: Identify actual and theoretical yields

Actual yield = 657 g, Theoretical yield = 865 g

Step3: Calculate percent yield

Percent yield = $\frac{657}{865}\times100\%$
Percent yield = $0.76\times100\% = 76.0\%$

Answer:

B. 76.0%
