Formula
The Molarity Calculator uses the formula:
Molarity (mol/L) = Moles of solute ÷ Solution volume
Worked example
For example, with moles of solute of 0.5 mol and solution volume of 2 L, the molarity (mol/l) is 0.2500.
| Moles of solute | 0.5 mol |
|---|---|
| Solution volume | 2 L |
| Molarity (mol/L) | 0.2500 |
|---|

Frequently asked questions
Molarity is the concentration of a solution in moles of solute per litre of solution: M = moles ÷ volume. 0.5 mol in 2 litres is 0.25 mol/L.
Divide the mass of solute by its molar mass. Then divide by the solution volume in litres to get molarity.
Molarity is in moles per litre (mol/L), often written as M. A 0.25 M solution has 0.25 moles of solute per litre.
No. Molarity uses the volume of the solution, while molality uses the mass of the solvent in kilograms.
The Molarity Calculator uses the formula: Molarity (mol/L) = Moles of solute ÷ Solution volume. For example, with moles of solute of 0.5 mol and solution volume of 2 L, the molarity (mol/l) is 0.2500.
