WebNov 30, 2024 · To compute the molality of a solute, you need to: Divide the amount of the solute (in moles) by the mass of the solvent (in grams). Alternatively, if the amount of the solute is unknown, multiply the mass of the solvent (in g) and its molar mass (in g/mol). Then divide the mass of the solute (in g) by the result from Step 2.
