    1 mole of any substance contains Avogadro's number.

    So, 1 mole of O2 = 6.023x10^23 molecules

    3 mole of O2 = 6.023x10^23x3 molecules

    = 1.8069x10^24 molecules

    Each molecule of Oxygen has 2 atoms.

    therefore,

    1.8069x10^24 molecules = 1.8069x10^24 x 2 atoms

    = 3.6138x10^24 atoms.
