Sagot :
Answer:
%m/m = 5,71%
Explanation:
En este caso, estamos hablando de un ejercicio de porcentaje masa/masa, y debemos aplicar la siguiente expresión o formula:
%m/m = msto / msol * 100 (1)
Donde:
msto: masa de soluto, en este caso los 12 g de nitrato de plata.
msol: masa de solución, en este caso los 210 g.
%m/m: porcentaje masa/masa o concentración porcentual que nos piden.
Todo lo que debemos hacer ahora es reemplazar los datos que el ejercicio nos da en la expresión (1) y llegaremos a la respuesta:
%m/m = 12 / 210 * 100
%m/m = 0,057 * 100
%m/m = 5,71%
Esta es la concentración porcentual de la solución.
Mucha suerte
