when is an oxygen atom a diatomic molecule?

The question was "What mass of sulfur contains half the number of atoms as 46.00 grams of oxygen?" Oxygen is 16 grams per mole but since it is a diatomic molecule wouldn't it be 32 grams per mole?

    Is Oxygen Diatomic

    Diatomic means 2 atoms that is it is a molecule of 2 atoms.

    So the mass of the molecule will be 32g/mole.

    But the mass of a single atom of oxygen will be 16g/mole.

    yes of course, you need to learn your diatomic molecules, halogens, oxygen, nitrogen and hydrogen are all diatomic, sulfur is S8 and phosphorus is P4 but thats irrelevent for now since this is obviously a high school chem question they dnt expect you to know that.
