Answer :

When the mass is the same, the number of molecules is inversely proportional to the molecular mass. This means less will be the molecular mass, more will be the number of molecules.


CO2 = 12 × 2 × 16 = 44u


N2 = 2× 14 = 28u


H2 = 2× 1 = 2u


CH4 = 12 + 4× 1 = 16u


Hence, 1 g H2 has maximum numbers of molecules.
