State and explain Graham's law of diffusion. 120 \(\mathrm{cc}\) of \(\mathrm{SO}_{2}\) gas is diffused through a porous membrane in \(40 \mathrm{~min}\). Under similar conditions, \(360 \mathrm{cc}\) of another gas is diffused in \(30 \mathrm{~min}\). What is the molecular weight of the other gas?
Why do the gases exert pressure?
State Graham's law of diffusion.
Derive the ideal gas equation on the basis of laws of Boyle, Charle and Avogadro. Calculate the volume occupied by an ideal gas at STP, if \(0.25 \ell\) of the gas is present at a pressure of \(700 \mathrm{~mm}\) of \(\mathrm{Hg}\) and \(273^{\circ} \mathrm{C}\).
