Molarity (M) is the number of moles of solute per liter of solution: M = moles of solute / liters of solution Example: You dissolve 4g of NaOH (molar mass = 40 g/mol) in 500 mL of water. 1. Convert grams to moles: 4g ÷ 40 g/mol = 0.1 mol 2. Convert mL to L: 500 mL = 0.5 L 3. Calculate: M = 0.1/0.5 = 0.2 M Useful dilution formula: M₁V₁ = M₂V₂ (when diluting a concentrated solution to a lower concentration).
