What is Molality?

Molality is a measure of the number of moles of solute present in 1 kg of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution. In the case of solutions with more than one solvent, molality can be defined for the mixed solvent considered as a pure pseudo-solvent. Instead of mole solute per kilogram solvent as in the binary case, units are defined as mole solute per kilogram mixed solvent. The term molality is formed in analogy to molarity which is the molar concentration of a solution. The earliest known use of the intensive property molality and of its adjectival unit, the now-deprecated molal, appears to have been published by G. N. Lewis and M. Randall in 1923.

How to Calculate Molality?
