Molality vs Moles of Solute
Fórmula
## How to Calculate Molality ### Formula **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.
Ejemplo Resuelto
Dissolve 0.5 moles of glucose in 1 kg of water.
- 01m = n / w
- 02m = 0.5 mol / 1 kg
- 03m = 0.5 mol/kg
Preguntas Frecuentes
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.
