4.0g of Oxygen has the fewest amount of atoms since H2 has more atoms than O2 (2 atoms) and Carbon (12/18 (if we include the electrons) atoms) also has more atoms than O2 (2 atoms).

0.5g of Hydrogen has the most amount of atoms - since Hydrogen is the least dense from them all. Hydrogen density - 0.08988 g/L Oxygen density - 1.429 g/L Carbon density - 2.25 grams per cubic centimeter

I tried to explain with the best of my ability.

    $\begingroup$ For homework questions we have a policy where you do not simply post the answer without explanation but rather that you give hints that lead the asker towards their own solution. We are not a homework completion service. $\endgroup$ – bon Jul 4 '16 at 13:00

  • $\begingroup$ No problem, I also added the explanations as Bon said. $\endgroup$ – DraggyWolf Jul 4 '16 at 13:25
