How to calculate molarity chemistry
Molarity measures the concentration of a solution as moles of solute per liter of solution — the most common concentration unit in chemistry.
How the calculation works
Molarity = Moles of solute ÷ Volume of solution (L).
Example
1.5 moles of solute in 3 liters of solution: 1.5÷3 = 0.5 mol/L (0.5 M).

Pro Tips for Molarity Chemistry
- Molarity is based on total solution volume, not solvent volume alone — the solute itself contributes to the final solution volume.
- Molarity changes slightly with temperature since solution volume can expand or contract, unlike molality which is temperature-independent.
Common Molarity Chemistry Mistakes to Avoid
- Using solvent volume alone (before the solute is added) instead of total final solution volume, which introduces a small but real error.
