1.0 L of

{N_2}

and 7/8 L of

{O_2}

at the same temperature and pressure were mixed together. What is the relation between the masses of the two gases in the mixture?

View answer and explanation

Correct option: C

{M_\mathrm{N}}_2 = {M_\mathrm{O}}_2

Option C (

{M_\mathrm{N}}_2 = {M_\mathrm{O}}_2

) is correct because at the same temperature and pressure, equal volumes contain equal number of moles. Given the ratio of volumes, we can determine the ratio of masses.

If for the gases, the critical temperatures are mentioned below i.e.

\begin{array}{cccccccccccccccccccc} {\underline {{\text{Gas}}} }&{\underline {\,{\text{Critical}}\,\,{\text{temperature}}} } \\ {\text{A}}&{{T_{{C_1}}}} \\ {\text{B}}&{{T_{{C_2}}}} \\ {\text{C}}&{{T_{{C_3}}}} \\ {\text{D}}&{{T_{{C_4}}}} \end{array}

{T_{{C_1}}} > {T_{{C_2}}} > {T_{{C_3}}} > {T_{{C_4}}}
