A container of volume 200 ~cm ^3 contains 0.2 mole of hydrogen gas and 0.3 mole of argon gas. The pressure of the system at temperature 200 ~K (R=8.3 ~J ~K ⁻¹ ~mol ⁻¹ ) will be

Step-by-step solution

We know that aligned & P V=n R T & P₁= n₁ V R T aligned gathered P₂= n₂ V R T P_ net =P₁+P₂ gathered aligned & = (n₁+n₂ ) R T V & =(0.2+0.3) 8.3 200 200 10⁻⁶ aligned =8.3 0.5 10^6=4.15 10^6 ~Pa
