Si desea preparar 300 gramos de una solución de azúcar en agua que tenga una concentración de 20% m/m en cuanto gramos de soluto

Digiron [165]

Answer:

$m_{soluto}=60g$

Explanation:

¡Hola!

En este caso, al considerar la unidad de concentración de porcentaje masa/masa, podemos escribir su fórmula como:

$\%m/m=\frac{m_{soluto}}{m_{solucion}}*100\%$

Podemos identificar la masa de soluto (azúcar) como la incógnita, y resolverla como se muestra a continuación:

$m_{soluto}=\frac{\%m/m*m_{solucion}}{100\%}\\\\m_{soluto}=\frac{20\%*300g}{100\%}\\\\m_{soluto}=60g$

¡Saludos!
