It is given by scientist avagadro. Defined as number of units of any substance. That is equal to 6.022 x 10^23 can tainting units like atoms, ions, etc...
Calculating 0.2 mole of oxygen gas
Oxygen gas that having two oxygen then now
=> 2 x 6.022 x 10^23
Since it has 0.2 moles
=> 2 (0.2) x 6.022 x 10^ 23
=> 0.4 (6.022 x 10^23)
=> 2.4088 x 10^23 atoms.
