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

Pressure exerted by saturated water vapour is called aqueous tension. What correction term will you apply to the total pressure to obtain the pressure of dry gas?

The rate of diffusion of a gas is directly proportional to which of the following?

$A$ gaseous mixture of $3$ gases $A$, $B$ and $C$ has a pressure of $10 \,atm$. The total number of moles is $10$. If the partial pressures of gases $A$ and $B$ are $3 \,atm$ and $1 \,atm$ respectively, and the molar mass of gas $C$ is $2 \,g/mol$, calculate the weight of $C$ in the mixture. (in $\,g$)
