In order to calculate the molality of a solution from its molarity, what other information would be needed?

Question

Quizplus · Accepted Answer

To calculate molality, we need to know the amount of solute (in moles) per kg of solvent. We already have the molarity (moles of solute per liter of solution), but we need to know the density of the solution to convert the volume of solution to mass of solvent. The molar mass of the solute is also needed to convert the number of moles to mass. Therefore, we need the molar mass of solute and density of solution.
