Molality vs Moles of Solute

Formel

m = n / w

Where:

m = molality (mol/kg)

n = moles of solute

w = mass of solvent in kilograms

Molality does not change with temperature because mass is temperature-independent.

Dissolve 0.5 moles of glucose in 1 kg of water.

What is molality?

Molality (m) measures concentration as moles of solute per kilogram of solvent. It is temperature-independent.

When should I use molality instead of molarity?

Use molality for colligative property calculations and when working at varying temperatures.

How do I convert molality to molarity?

You need the density of the solution. M = m × d / (1 + m × Mw/1000), where d is density and Mw is molar mass of solute.
