Question

1. a chemical reaction that theoretically could produce 200 g of substance only produces 140 g. what is the percent yield in this reaction? enter the correct answer in the box. % yield

Explanation:

Step1: Recall percent yield formula

Percent yield = $\frac{\text{Actual yield}}{\text{Theoretical yield}} \times 100\%$

Step2: Plug in given values

Actual yield = 140 g, Theoretical yield = 200 g
Percent yield = $\frac{140}{200} \times 100\%$

Step3: Calculate the result

$\frac{140}{200} = 0.7$, $0.7 \times 100\% = 70\%$

Answer:

70
