Question
If 5.00 g of NaCl are dissolved in 25.0 g of water, the percent mass (m/m) of this soluton isGroup of answer choices15516.7200.2
Solution
Para calcular el porcentaje en masa (m/m) de una solución, se utiliza la siguiente fórmula:
Donde:
- La masa del soluto (NaCl) es 5.00 g.
- La masa del solvente (agua) es 25.0 g.
- La masa de la solución es la suma de la masa del soluto y la masa del solvente.
Primero, sumamos las masas del soluto y del solvente para obtener la masa total de la solución:
Luego, aplicamos la fórmula del porcentaje en masa:
Por lo tanto, el porcentaje en masa (m/m) de la solución es 16.7%.
