Example: 2.0 mol × (6.022 × 10²³ molecules/mol) = 1.2 × 10²⁴ CO₂ molecules. Each SO₂ molecule contains one sulfur atom. 1.78 mol × (6.022 × 10²³ atoms/mol) = 1.07 × 10²⁴ sulfur atoms. Each Na₂SO₄ formula unit contains two sodium atoms. 0.980 mol × (6.022 × 10²³ formula units/mol) × 2 = 1.18 × 10²⁴ sodium atoms. (7.4 × 10²³ formula units) ÷ (6.022 × 10²³ formula units/mol) = 1.2 mol CaO. (2.88 × 10²⁴ molecules) ÷ (6.022 × 10²³ molecules/mol) = 4.78 mol NO.
