Molarity

Calculate molarity from solute amount and total solution volume.

How this calculator works

Enter the values for first value, second value and review the units before calculating.

Formula / method

M = moles ÷ liters of solution

Worked example

0.5 mol in 2 L of solution has a concentration of 0.25 M.

Assumptions and limitations

Volume is final solution volume in liters and the solute amount is in moles.

Temperature, activity coefficients and dissolution chemistry are not modeled.
