Introduction to Osmolarity Calculation

Osmolarity refers to the concentration of a solute in a solution and is expressed as the number of osmoles of solute per liter of solution. The osmolarity calculation is based on the product of the solute concentration (in moles per liter), the molar mass of the solute, and the volume of the solution (in liters). By multiplying these three factors, the osmolarity of the solution can be determined.

Parameter usage:

Example valid values:


Data validation

The concentration, solute molar mass, and solution volume should each be greater than zero.


This calculator assists in determining the osmolarity of a solution based on the specified concentration of solute, molar mass of the solute, and volume of the solution.
