1 mole of any molecule contains 6.022 * 10^23 molecules
32 gm of oxygen = 1 mole
Therefore, 16 gm of oxygen = 0.5 mole
Hence, 0.5 moles of molecules of oxygen contains 0.5 * 2 * 6.022 * 10^23 atoms
(1 molecule of oxygen contains 2 atoms)
Total no. of atoms in 16 gm of oxygen
= 6.022 * 10^23
Hope it helped you
