3. 0.5 moles of H = 0.5× 6.023× 10^23 molecules of H

4 g of H = 4× 6.023× 10^23 molecules of H

18 g of H2O = 6.023× 10^23 molecules of H2O

28 g of CO = 6.023× 10^23 molecules of CO

so 2.2 g of CO = 2.2/28 × 6.023× 10^23 molecules of CO

so the increasing number of molecules would be

2.2g of CO < 0.5 moles of H< 18 g of water<4 g of H

ans would be (b) (iv)<(i)<(iii)<(ii)
