1\,\,\mathrm{litre}

of a gas

A

at 600 mm and 0.5 litre of gas

B

at 800 mm are taken in a

2\,\,\mathrm{litre}

bulb. The resulting pressure is:

View answer and explanation

Correct option: D

500\mathrm{ }mm

Option D is correct because, according to Dalton's Law of Partial Pressures, the total pressure is the sum of the partial pressures. P_total = (P1V1 + P2V2)/V_total = (600*1 + 800*0.5)/2 = 500 mm

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}}}
