Molarity Formula

M = n/V
Molarity = Moles of Solute / Volume of Solution

Variables

  • M - Molarity (in mol/L)
  • n - Moles of solute (in mol)
  • V - Volume of solution (in L)

Units

  • Molarity: M, mM, μM, nM, pM
  • Volume: L, mL, μL, cm³, dm³
  • Moles: mol (standard unit)

Frequently Asked Questions

What is molarity?

Molarity (M) is a measure of concentration that represents the number of moles of solute per liter of solution. It is one of the most commonly used concentration units in chemistry.

How is molarity different from molality?

Molarity (M) is moles of solute per liter of solution, while molality (m) is moles of solute per kilogram of solvent. Molarity depends on temperature and pressure, while molality does not.

What units are supported?

The calculator supports multiple units for volume (L, mL, μL, cm³, dm³) and molarity (M, mM, μM, nM, pM). All conversions are handled automatically.

Can I use this for dilution calculations?

This calculator is specifically for calculating molarity from moles and volume. For dilution calculations (M1V1 = M2V2), you would need a separate dilution calculator.

Is my data secure?

Yes, all calculations happen locally in your browser. Your data never leaves your device.

Can I use this offline?

Yes, once loaded, the calculator works completely offline in your browser.
