Concentration lectures » molality

Molality is defined in such a way that it is independent of temperature changes:

molality definition, eq. 8.18.1

and is expressed in [mole/kg] units. While rarely used in analytical chemistry, molality is used quite often in physical chemistry, especially when dealing with substance properties over the wide temperature range, or properties changing with both temperature and mixture composition.

For example of molality conversion see percentage to molality section.
