I know Oxygen is diatomic, but I'm still confused. If it has twice as many atoms, what differene does that make- you still have the same number of atoms, 6.02x10^23. What difference does it make if they are paired up? Unless the atomic mass of ONE Oxygen atom is 16.00, is that it? Please explain it to me. Thanks.

But if a mole is a set number 6.02x10^23, then its still the same NUMBER of atoms- they are just paired. EXPLAIN it to me- a stupid answer like 16x2=32 doesn't help.

On the periodic table it is showing 16 for the molar mass of monatomic oxygen. When an O atom bonds with another O atom they become one unit.
Think of it as having a mole of O atoms bonded with a mole of O atoms yielding one mole of diatomic oxygen.
Each mole is 16g so when the two come together to form one mole of O2 one mole would be 32g.
Does this help? I hope so!

Remember: a mole can be 6.022*10^23 of anything.
You can have a mole of two atoms bonded together.

O = Oxygen that has an atomic weight of 16
O2 = the symbol for a molecule of Oxygen
A moelecule is the smallest , stable, form of an element
A mole of anything is the the stable form, and the G/mol is the grams of an element needed to make a mole.
Therefore the the g/mole of Oxygen (O2) is 32
The g/mole of water is 18 (H2 = 2 + O=16 ==18)
Hopes this clears you up

your question kind of confuses me, but i'll try to see if i can clarify anything.
yes, a single atom of oxygen is 16.00g/mol.
i feel like you're contradicting yourself here: "If it has twice as many atoms, what differene does that make- you still have the same number of atoms, 6.02x10^23. What difference does it make if they are paired up?"
you would have twice the number of atoms in O2. you would need two moles of monatomic Oxygens to make 1 mole of O2's. are you confusing molecule with atoms, perhaps? because you would have a mole of molecules in 6.022x10^23 molecules of O2, and 2x avogrado's number of just... oxygen atoms.
i hope that helped a bit.
