The mole fraction of a solvent in aqueous solution of solute is 0.6 the molality of the aqueous solution is

The question seems to be incomplete. To calculate the molality of the solution, we need more information such as the mass of the solvent or the number of moles of the solute.

However, I can explain the terms and the general formula for you:

1. Mole fraction is the ratio of the number of moles of a component to the total number of moles of all components in the mixture. In this case, the mole fraction of the solvent is given as 0.6.

2. Molality (m) is defined as the number of moles of solute per kilogram of solvent. It is expressed in mol/kg.

The formula to calculate molality is:

m = moles of solute / mass of solvent in kg

Without the values for the moles of solute or the mass of the solvent, we cannot calculate the molality of the solution.
