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.

    计算示例

    Dissolve 0.5 moles of glucose in 1 kg of water.

    1. m = n / w
    2. m = 0.5 mol / 1 kg
    3. m = 0.5 mol/kg
