molarity = 1.0 M Molality (m) Molalityis the number of moles of solute per kilogram of solvent. Because the density of water at 25°C is about 1 kilogram per liter, molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, ...

To convert from molarity to molality, you need to know the density of the solution. The formula for converting from molarity to molality is: Molality (m) = Molarity (M) / density (g/mL). To convert from molality to molarity, you need to know the density of the solvent. The f...
