    32.00 g

    Explanation:

    The molar mass of one atom of oxygen is 16 g/mol.

    So for the molecular oxygen or diatomic oxygen O₂:

    2 * 16 g/mol

    32 g/mol.

    16 g of oxygen = one mole of oxygen = 6.022 * 10²³ atoms of oxygen

    For O₂.

    32 g of oxygen = one mole of oxygen = 6.022 * 10²³ molecules of oxygen

    The number 6.022 * 10²³ is called Avogadro number.

    It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
