Molality
What is Molality?
Molality (m) is a measure of solute concentration expressed as the number of moles of solute per kilogram of solvent. Unlike molarity, molality is independent of temperature because it is based on mass rather than volume. It is used in calculations involving colligative properties such as boiling point elevation and freezing point depression, where it is the preferred concentration unit.
