Web30 nov. 2024 · What is the molality if there are 3 moles in 0.5 kg of solvent? The answer is 6 mol/kg. To see how this result is derived, recall that the formula for molality reads: molality = moles of solute / mass of solvent (kg). Plugging in moles of solute = 3 and mass of solvent = 0.5 kg, we obtain molality = 3 / 0.5 = 6 mol/kg.
