What do you want to calculate?
Volume unit
Molarity (M) = moles of solute / liters of solution. mL are automatically converted to L.

Enter values to see the molarity calculation.
Molarity is expressed in moles per liter (mol/L or M). Common in chemistry for solution concentrations.
How to Use
- Select what to calculate :- Choose Molarity, Moles, or Volume
- Enter known values :- Fill in the two known quantities
- Select volume unit :- Choose L or mL (mL auto-converts to L)
- Click Calculate :- View the result with step-by-step formula
Note: M = n / V where M = molarity (mol/L), n = moles of solute, V = volume of solution in liters. Example: 2 mol รท 4 L = 0.5 M.
