Air at sea level is dense. This is a practical application of

The $O_2$ gas is collected over water at $400 \ K$ temperature in a $2 \ L$ vessel. If the total pressure of the mixture is $33.26 \ bar$ and the pressure of dry $O_2$ gas is $32.20 \ bar$,find the vapour pressure of water under the same conditions.

What is the ratio of the rates of diffusion of gases $A$ and $B$ having molecular weights $36$ and $64$ respectively?

Isochores are drawn at

For which of the following gas mixtures does Dalton's law of partial pressure $NOT$ apply?

At $STP$,it takes $1200 \ s$ for $0.48 \ g$ of $O_2$ to effuse through a pinhole. How many $mL$ of $CO_2$ gas will effuse under the same conditions and in the same time?
