If the rate of diffusion of gas $A$ is five times that of gas $B$,what will be the ratio of the densities of $A$ and $B$?

Provide the mathematical expression for Dalton's law of partial pressure.

$A$ certain volume of oxygen gas diffuses through a porous pot in $20 \ s$. If the same volume of another gas $(X)$ diffuses in $Y \ s$, then $(X)$ and $Y$ respectively are:

The rates of diffusion of $SO_2$, $CO_2$, $PCl_3$ and $SO_3$ are in the following order:

The ratio of rates of diffusion of oxygen and an unknown gas is $1:4$. The unknown gas is

At which of the following conditions will the density of nitrogen be maximum?
