Stoichiometry

Molarity Calculator

Solve for moles, volume, or molarity using M = n / V.

M = n / V

Run this calculator

Leave a nullable field blank to solve for it.

Amount of solute in moles. Set to null to solve for moles.

Solution volume in liters. Set to null to solve for volume.

Molarity (mol/L). Set to null to solve for concentration.

Formula

This calculator uses the equation below. Use it as a quick reference when checking setup before solving.

M = n / V

Variable glossary

Moles (moles)

Amount of solute in moles. Set to null to solve for moles.

Volume (volume)

Solution volume in liters. Set to null to solve for volume.

Concentration (concentration)

Molarity (mol/L). Set to null to solve for concentration.

Frequently Asked Questions

What does the Molarity calculator solve?

It solves Molarity problems in stoichiometry using your provided inputs and computes unknown values when nullable fields are left blank.

Do I need to convert units before using this tool?

Use the unit toggles where available (for example K/C and L/mL). ChemGenius converts values to the calculator's base units automatically before solving.

Can I save this result in my workflow?

Yes. After computing a result, you can continue into ChemGenius workflows like protocol drafting or notes to keep your calculation context attached to downstream work.
