Vedclass · Answer

(D) To find the number of molecules,we calculate the number of moles $(n = 	ext{mass} / 	ext{molar mass})$ and multiply by Avogadro's number $(N_A)$:$A) \ 16 \ g \ O_2: n = 16 / 32 = 0.5 \ mol$$B) \ 16 \ g \ NO_2: n = 16 / 46 \approx 0.348 \ mol$$C) \ 7 \ g \ N_2: n = 7 / 28 = 0.25 \ mol$$D) \ 2 \ g \ H_2: n = 2 / 2 = 1.0 \ mol$Since $H_2$ has the highest number of moles $(1.0 \ mol)$,it contains the maximum number of molecules.
