$2.9 \mathrm{g}$ of a gas at ${95}^{\mathrm{o}}\mathrm{C}$ occupied the same volume as $0.184 \mathrm{g}$ of dihydrogen at $17\mathrm{}°\mathrm{C},$ at the same pressure. What is the molar mass of the gas?

A mixture of dihydrogen and dioxygen at one bar pressure contains $20\mathrm{\%}$ by weight of dihydrogen. Calculate the partial pressure of dihydrogen.

What would be the $\mathrm{SI}$ unit for the quantity $\raisebox{1ex}{${\mathrm{PV}}^2{\mathrm{T}}^2$}\!\left/ \!\raisebox{-1ex}{$\mathrm{n}$}\right.$ ?

In terms of Charles’ law explain why $–{273}^{\mathrm{o}} \mathrm{C}$ is the lowest possible temperature.

Critical temperature for carbon dioxide and methane are ${31.1}^{\mathrm{o}} \mathrm{C}$ and $–{81.9}^{\mathrm{o}} \mathrm{C}$ respectively. Which of these has stronger intermolecular forces and why?

Air is cooled from ${25}^{°} \mathrm{C}$ to $0^{°} \mathrm{C}$. Calculate the decrease in rms speed of the molecules.

Find the rms, most probable and average speeds of ${\mathrm{SO}}_2$ at ${27}^{° }\mathrm{C}$.

Find the rms, most probable and average speeds of ${\mathrm{O}}_2$ at ${27}^{° }\mathrm{C}$.
