As we know, the higher the number of moles of a gas, it will have higher the number of molecules.

\\\text { Mole of } \mathrm{H}_{2}=\frac{4}{2}=2 \\\\ \text { Mole of } \mathrm{He}=\frac{112}{22.4}=5\\\\ \text { Mole of } CaCO_{3}=\frac{200}{100}=2 \\\\ \text { Mole of } NH_{3}=\frac{33.6}{22.4}=1.5\\\\ \text{He has maximum number of molecules.}
