Question
- 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
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%: $0.7 \times 100\% = 70\%$
