Formula

M = m / (Mo × V)

Where: M = Molarity, m = Mass, Mo = Molar Mass, V = Volume

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)

Milligram (mg)= 1,000 mg
Microgram (μg)= 1,000,000 μg
Kilogram (kg)= 0.001 kg
Nanogram (ng)= 1,000,000,000 ng

2. Convert Molar Mass to g/mol

Milligram/mol (mg/mol)= 1,000 mg/mol
Microgram/mol (μg/mol)= 1,000,000 μg/mol
Kilogram/mol (kg/mol)= 0.001 kg/mol
Nanogram/mol (ng/mol)= 1,000,000,000 ng/mol

3. Convert Volume to Liters (L) or dm³

Milliliter (mL)= 1,000 mL
Centimeter³ (cm³)= 1,000 cm³
Meter³ (m³)= 0.001 m³
Microliter (μL)= 1,000,000 μL

4. Convert Molar Concentration to mol/L or mol/dm³

Millimolar (mmol/L)= 1,000 mmol/L
Micromolar (μmol/L)= 1,000,000 μmol/L
Nanomolar (nmol/L)= 1,000,000,000 nmol/L
Picomolar (pmol/L)= 1,000,000,000,000 pmol/L

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!
