What is Molarity
Molarity is the concentration of a solution defined as moles of solute per liter of solution.
Molarity (M) = Mass of Solute (g) / Molar mass (g/mol) × Volume (L)
Equivalently, M = number of moles / volume of solution.
Units of Molarity
Molarity is commonly expressed as mol/L (also written as mol·L⁻¹ or simply M).
- mol/L
- mol·L⁻¹
- M (molar)
Units to Consider Before Calculating Molarity
If you want to calculate molarity accurately, it's very important to pay attention to the units of the values provided. Examine a few you values of different units, which will help you understand the required unit table during the calculation.
1. Convert Mass to Grams (g)
2. Convert Molar Mass to g/mol
3. Convert Volume to Liters (L) or dm³
4. Convert Molar Concentration to mol/L or mol/dm³
Good News!
Our molarity calculator automatically converts great units into the required units before applying the formula—so you don't have to worry about unit conversions yourself!
