Molarity Formula — M = n/V

📖 What is Molarity?

Molarity (also called molar concentration) measures the number of moles of solute dissolved per litre of solution. It is the most common way to express solution concentration in chemistry.

M = n / V

🔤 What Each Variable Means

M

Molarity (mol/L or M)The concentration of the solution

n

Moles of solute (mol)Amount of the dissolved substance

V

Volume of solution (litres, L)The total volume of the solution (not just solvent)

📝 Step-by-Step Example

Dissolve 2 mol of NaCl in water to make 0.5 L of solution. What is the molarity?

1

Identify valuesn = 2 mol V = 0.5 L

2

Apply formulaM = n / V = 2 / 0.5

✓

Answer: M = 4 mol/L (4 M)
