Answer 1

Explanation:

(a) The mass of 1 mole of oxygen atoms = 16 g

Thus, the mass of 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g

b) The mass of 1 mole of water molecules = 18 g

Thus, the mass of 0.5 mole of water molecules = 18 × 0.5 = 9.0 g

in this method you can do but this not answer but ssame process
