Chemistry - Ideal Gas Question with Solution | TestHub

Two students perform experiments on two identical gaseous mixture (He gas, just saturated with water vapours) in identical containers with some drying agent but at different temperature ( $27^{\circ }\mathrm{C}$ and $47^{\circ }\mathrm{C}$, respectively).

Student-I : When the gaseous mixture entered into the container, immediately after admission, the pressure in the flask is 800 torr and after standing for some time, the pressure reaches a constant value of 760 torr.

Student-II : When gaseous mixture enters, the mass of drying agent increases by 0.2 g  after standing for some time.

Find the volume of the container.

Assume vapour pressure of water ∝ T² in between 20°C to 50°C.

[Use : R = 0.08 atm/mol-K, T = temperature in Kelvin]
