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

Explanation:

Step1: Define percent yield formula

La fórmula del rendimiento porcentual es $\text{Rendimiento porcentual} = \frac{\text{Rendimiento real}}{\text{Rendimiento teórico}} \times 100\%$

Step2: Sustituir los valores dados

Sustituimos el rendimiento real (140 g) y el teórico (200 g):
$\text{Rendimiento porcentual} = \frac{140}{200} \times 100\%$

Step3: Calcular el resultado

Primero calculamos la fracción: $\frac{140}{200} = 0.7$, luego multiplicamos por 100%: $0.7 \times 100\% = 70\%$

Answer:

70%
