Answer:
Half mole or 0.5 moles
__________________________________________________________
Solve
Oxygen has a molar molar mass of 32 g.
This means that O2 will have half that amount of grams, half-mole-substance.
6.022*10^23 molecules are present in one mole of any substance, so half it for O2.
6.022 × 10²³
3.011 × 10²³
And simplified, that would make your answer 0.5 moles.
