Editing Molality (section)

=== Advantages ===
The primary advantage of using molality as a measure of concentration is that molality only depends on the masses of solute and solvent, which are unaffected by variations in temperature and pressure. In contrast, solutions prepared volumetrically (e.g. [[molar concentration]] or [[mass concentration (chemistry)|mass concentration]]) are likely to change as temperature and pressure change. In many applications, this is a significant advantage because the mass, or the amount, of a substance is often more important than its volume (e.g. in a [[limiting reagent]] problem).

Another advantage of molality is the fact that the molality of one solute in a solution is independent of the presence or absence of other solutes.
