How to Calculate Molarity

Formula

M = n / V

Where:

  • M = molarity (mol/L)
  • n = moles of solute
  • V = volume of solution in liters

    • Molarity expresses concentration as moles of solute per liter of solution.

    Example Calculation

    You dissolve 0.5 moles of NaCl in 1 liter of water.

    1. 01M = n / V
    2. 02M = 0.5 mol / 1 L
    3. 03M = 0.5 M
