How to use Molarity Calculator

Provide the solute amount and the total solution volume, and the calculator will express the concentration as molarity.

This calculator is for chemistry classes, lab prep, and dilution work where concentration must be stated in moles per liter.

Use the final solution volume, not just the solvent volume, when calculating molarity.
If the volume was measured in milliliters, convert it to liters before interpreting the result.
