$2 \ g$ $H_2$

Vedclass · Answer

(B) The number of molecules is directly proportional to the number of moles $(n = \frac{	ext{mass}}{	ext{molar mass}})$.$7 \ g$ $N_2 = \frac{7}{28} = 0.25 \ mol$$2 \ g$ $H_2 = \frac{2}{2} = 1 \ mol$$16 \ g$ $NO_2 = \frac{16}{46} \approx 0.348 \ mol$$16 \ g$ $O_2 = \frac{16}{32} = 0.5 \ mol$Since $2 \ g$ $H_2$ has the highest number of moles $(1 \ mol)$,it contains the maximum number of molecules.
