The root means square velocity of hydrogen at $STP$ is $1.83 \times 10^5 \,cm \, sec^{-1}$ and its means free path is $1.78 \times 10^{-5} \,cm$ . What will be the collision number at $STP$ ?

The reduced volume and reduced temperature of a gas are $10.2$ and $0.7$ respectively. If its critical pressure is $4.25\, atm$ then its pressure will be

$20\, dm^{3}$ of $SO_{2}$ diffuse through a porous partition in $60\, s$. What volume of $O_{3}$ will diffuse under similar conditions?

A gaseous mixture containing $He,\, CH _{4}$ and $SO _{2}$ was allowed to effuse through a fine hole then find what molar ratio of gases coming out initially? (Given mixture contains $He,\, CH _{4}$ and $SO _{2}$ in $1: 2: 3$ mole ratio $)$.

Above the Boyle temperature, the compressibility factor of the real gases, $Z$ is
