Описание к видео One mole of a mixture of \( \mathrm{N}_{2}, \mathrm{NO}_{2} \) and ...

One mole of a mixture of \( \mathrm{N}_{2}, \mathrm{NO}_{2} \) and \( \mathrm{N}_{2} \mathrm{O}_{4} \) has a mean molar mass of \( 55.4 \). On heating to a temperature at which all the \( \mathrm{N}_{2} \mathrm{O}_{4} \) may be presumed to have dissociated : \( \mathrm{N}_{2} \mathrm{O}_{4} \longrightarrow 2 \mathrm{NO}_{2} \), the mean
\( \mathrm{P} \) molar mass tends to the lower value of \( 39.6 \). What is the mole ratio of \( \mathrm{N}_{2}: \mathrm{NO}_{2}: \mathrm{N}_{2} \mathrm{O}_{4} \) in the original

W mixture?
(A) \( 0.5: 0.1: 0.4 \)
(B) \( 0.6: 0.1: 0.3 \)
(C) \( 0.5: 0.2: 0.3 \)
(D) \( 0.6: 0.2: 0.2 \)
