There is 6.0210^23 molecule per mole. And there is 2 atoms per oxygen molecule. So the answer is 1.20410^24 atoms in 1.0 mole of O2.

Answer: The number of atoms in given amount of oxygen gas is \(6.022\times 10^{23}\)

Explanation:

According to the mole concept:

1 mole of a substance contains \(6.022\times 10^{23}\) number of atoms.

We are given:

Moles of oxygen gas = 1 mole

So, the number of atoms that will be present in 1 mole of oxygen gas will be \(1\times 6.022\times 10^{23}=6.022\times 10^{23}\) number of atoms.

Hence, the number of atoms in given amount of oxygen gas is \(6.022\times 10^{23}\)
