The equivalence factor I should use should involve the Avogadro Number which is 6.02 * 10²³.

6.02 * 10²³ molecules of Oxygen are present in 1 mole of Oxygen molecule.

4.28 * 10¹⁹ molecules of Oxygen would be:

= 4.28 * 10¹⁹ * 1 / (6.02 * 10²³)

≈ 0.0000711 moles

So 4.28 * 10¹⁹ molecules of Oxygen is ≈ 0.0000711 moles
