Calcular la m y M de una concentración Porcentual 45% m/m, la cual tiene una D solución 1.25 g/ml y una masa de sto de 125g. HN03

Explanation:

Calculate the "m" and "M" of a percentage concentration of 45% m / m, which has a solution D 1.25 g / ml and a mass of 125g.

Given data is:

The mass % of the solution is 45%.

The density of the solution is 1.25 g/mL.

The mass of the solution is 125 g.

Molarity of solution is:

The volume of the solution is:

From mass% of the solution, the mass of solute HNO_3 can be calculated.

The number of moles of HNO3 is :

The molarity is:

The molality is:
