Three grams of helium diffuses from a container in $15 \min$. The mass of sulphur dioxide diffusing from the same container over the same time interval will be

In $5 \mathrm{s}$, the volume $\mathrm{X}$of ${\mathrm{H}}_2$ gas effuses through a hole in a container. The time taken for the effusion of the same volume of the specified gas under identical conditions is

The degree of dissociation $\left(\mathrm{\alpha }\right)$ of the reaction ${{\mathrm{A}}_2}_{\left(\mathrm{g}\right)}\rightleftharpoons 2{\mathrm{A}}_{\left(\mathrm{g}\right)}$  in terms of rate of diffusion $\left({\mathrm{r}}_{mix}\right)$ of equilibrium mixture and that of a reference gas $\mathrm{C}$ is given by: 

where $\mathrm{M}$ stands for the respective molar masses.

If ${\mathrm{X}}_{\mathrm{M}}, {\mathrm{X}}_{\mathrm{P}}$ and ${\mathrm{X}}_{\mathrm{V}}$ are mole fraction, pressure fraction and volume fraction, respectively, of a gaseous mixture, then:

$1000 \mathrm{mL}$ of a gas $\mathrm{A}$ at $600 \mathrm{torr}$ and $500 \mathrm{mL}$ of gas $\mathrm{B}$ at $800 \mathrm{torr}$ are placed in a $2 \mathrm{L}$ flask. The final pressure will be:

On which of the following mixtures is Dalton's law not applicable? 

Which of the following depicts Graham's law? 

A balloon filled with ethylene is pricked with a needle and quickly dropped in a tank of ${\mathrm{H}}_2$ gas under identical conditions. After a while, the balloon will not:
