Answer:

141.7 de Agua deben ser adicionados para preparar la solución deseada

Explanation:

El %m/m se define como la masa de soluto (En este caso, sulfato de cobre) en 100g de solución (Sulfato de cobre + Agua):

%m/m = Masa soluto / Masa soluto + Masa Agua *100

Reemplazando con los datos del problema:

15%m/m: 25g CuSO₄ / (25g CuSO₄ + Xg H₂O) * 100

0.15 = 25 /(25+X)

3.75 + 0.15X = 25

0.15X = 21.25

X = 141.7 de Agua deben ser adicionados para preparar la solución deseada
