? Only give the numeric value of your answer. Don’t include the units.

The number of moles of O atom in mol of = 1.6

Explanation:

1 molecule of contains 2 atoms of O

So, molecules of   contains atoms of O.

We know that 1 mol of an atom/molecule/ion represents numbers of atoms/molecules/ions respectively.

So, molecules of   is equal to 1 mol of .

atoms of O is equal to 2 moles of O atom.

Hence, 1 mol of contains 2 moles of O atom.

Therefore, mol of contains moles of O atom or 1.6 moles of O atom.
