Percentage to Molarity Calculator

How to Use This Calculator

Enter the percentage concentration (% w/v), molar mass of the solute, and density of the solution. The calculator will automatically convert the percentage concentration to molarity.

What This Calculator is Used For

This calculator is useful for converting weight/volume percentage concentration of a solution into molarity (mol/L), a common unit used in chemistry for measuring the concentration of a solute in a solution.

Formula Used

Molarity (mol/L) = (Percentage × Density × 10) / Molar Mass

Example

If you have a 5% w/v NaCl solution, a density of 1.02 g/mL, and a molar mass of 58.44 g/mol:
M = (5 × 1.02 × 10) / 58.44 ≈ 0.873 mol/L
