Se toman 200 ml de una disolución de un frasco de ácido clorhídrico ClH en cuya etiqueta se lee: Pureza: 35 % en peso; densidad = 1,15 g/ml. ¿Cuál es su concentración en g/l?

Concentration of solution is 402g/mL

Explanation:

The HCl solution has a purity of 35% w/w. That means there are 35g of HCl per 100g of solution. As density of solution is 1.15g/mL, volume of the solution is:

100g solution × (1mL / 1.15g) = 86.96mL. Thus concentration of solution in g/mL is:

35g of HCl / 86.96mL = 0.402g/mL. As 1L contains 1000mL:

= 402g/mL

Concentration of solution is 402g/mL
