There is 6.02*10^23 molecule per mole. And there is 2 atoms per oxygen molecule. So the answer is 1.204*10^24 atoms in 1.0 mole of O2.

Answer: The number of atoms in given amount of oxygen gas is
6.022* 10^(23)

Step-by-step explanation:

According to the mole concept:

1 mole of a substance contains
6.022* 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* 6.022* 10^(23)=6.022* 10^(23) number of atoms.

Hence, the number of atoms in given amount of oxygen gas is
6.022* 10^(23)
