Answer:

Explanation:

MOLES OF OXYGEN =0.2

∵ No. of molecules = moles × NA

∴ Moles = Molecules / NA

            = 0.20 / 6.02×10²³

            0.0332×10-²³

Now No. of atoms = moles × NA ×atomicity

                   

                            = 3.32×10^-25×6.02×10²³ × 2

                            = 39.97 ×10^-2
