# Moles! 22.4L at stp

1. Why does O2 is 6.02 x10 to 23 equal one mole? Wouldn't it actually equal 2 moles since there are two oxygen atoms? I know that a mole is 620000000000000000000000 of anything but there are two oxygen atoms even if they're covalently bonded. And therefore it gets me confused that one atom can fill 22.4L if it is a gas but o2 can also fill 22.4L if it was a gas too? Wouldn't it fill 44.8L since it's double the amount of atoms.. Can anyone help of with explaining this please? I know it sounds stupid but I'd like to clear this up please thanks﻿
2. 6.02 x10 ^23 : number of moles for 1 molecule(O2)/ atom (O)/ compound/ isotope
Oxygen is a diatomic molecule so it only exists as O2. It's not possible for just one O atom to fill anything since it doesn't exist.
Same goes with hydrogen, nitrogen, fluorine, iodine, chlorine, bromine
