Web25 jul. 2024 · Molarity deals with liters of solution, while molality deals with kilograms of solvent. A solution is a mixture of solvent and solute; a solvent is the medium into which the solute is mixed. A further complication to the molarity/molality confusion is how to distinguish between their variables and units.
Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent.
