How is molality used?
Molality involves moles: it is the ratio of moles of solute to kilograms of solvent. Molarity, on the other hand, which should not be confused with molality, is the ratio of moles of solute to liters of solution. Colligative (collective) property calculations tend to use molality as opposed molarity.
