HEYYA FRND..
__________

16 g i equal to 0.5 mole of oxygen molecule.
we know in one molecule of oxygen there are 2 atom. Hence in 0.5 mole of oxygen molecule, there are 0.5 * 2 mole of atom of oxygen. that is 1 mole of oxygen atom.

Number of particle in one mole = 6.022 * 10^233.

Thu number of atom in 16 g of oxygen gas = 6.022*10^23..
