The molality of 19.5 % sodium chloride (NaCl) dissolved in water is to be determined. Concept Information: Molal concentration is the ratio of the number of moles of the solute to the mass of the solvent in kilograms, which is water in this case. Molality is independent of pressure or temperature changes. Molality is different from molarity as the latter does not involve volume, which changes with temperature an is known as a dependent variable.
