What weight of hydrogen at STP could be contained in a vessel that holds $3.36 \mathrm{L}$ gas at STP? 

Volume of oxygen measured at STP obtained by heating $2.16 \mathrm{g}$ of $\mathrm{HgO} \left(\mathrm{Hg} =200\right)$ is
$2\mathrm{HgO}\stackrel{∆}{\to } 2\mathrm{Hg} + {\mathrm{O}}_2$ 
 

A flask of gaseous ${\mathrm{CCl}}_4$ was weighed at measured temperature and pressure. ${\mathrm{CCl}}_4$ was replaced by ${\mathrm{O}}_2$ at the same temperature and pressure. The mass of the ${\mathrm{CCl}}_4$ vapour will be 

Which is not a correct representation of Boyle's law?

A quantity of gas is collected in a graduated tube over the mercury. The volume of gas at $18°\mathrm{C}$ is $50.0 \mathrm{mL}$ and the level of mercury in the tube is $100$torr above the outside mercury level. The barometer reads $750$ Torr. Hence, volume at STP is approximately.

What percent of a sample of nitrogen must be allowed to escape if its temperature, pressure, and volume are to be changed as given below,

: $273{}^0\mathrm{C}, 3.00 \mathrm{atm},1.65 \mathrm{L} \to 0{}^{\mathrm{o}}\mathrm{C}, 0.75 \mathrm{atm} 0.55\mathrm{L}$.

Which of the assumptions of the kinetic molecular theory best explains the observation that a balloon collapses when exposed to liquid nitrogen (which is much colder than a cold winter day)? 

On a ship sailing in Pacific Ocean where temperature is $23.4^{°} \mathrm{C}$, a balloon is filled with $2 \mathrm{L}$ air. What will be the volume of the balloon when the ship reaches the Indian Ocean, where temperature is $26.1^{°} \mathrm{C}$?
