Osmolarity and osmolality are units of solute concentration that are often used in reference to biochemistry and body fluids. While any polar solvent could be used, … Molality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. A commonly used unit for molality in chemistry is mol/kg. A solution of concentration 1 mol/kg is also sometimes … See more The molality (b), of a solution is defined as the amount of substance (in moles) of solute, nsolute, divided by the mass (in kg) of the solvent, msolvent: In the case of … See more Advantages The primary advantage of using molality as a measure of concentration is that molality only … See more Molality appears in the expression of the apparent (molar) volume of a solute as a function of the molality b of that solute (and density of the solution and solvent): See more The term molality is formed in analogy to molarity which is the molar concentration of a solution.
