Question

1 mol of P4 contains

Answer 1

24.088 × 10²³ atoms of P

Explanation:

1 mole of any substance = Avogadro's number

Avogadro's number = 6.022 × 10²³

Each molecule of P₄ contains 4 atoms of P

∴ 1 mole of P₄ = 4 × 6.022 × 10²³

                       = 24.088 × 10²³

1 mole of P₄ will contain 24.088 × 10²³  atoms of P
