The density of nitrogen monoxide $(NO)$ at $S.T.P.$ is ......... $g \ L^{-1}$.

Which of the following expressions at constant pressure represents Charles's law?

If a gas occupies a volume of $1.5 \, L$ at a pressure of $75 \, cm \, Hg$,then at the same temperature,the volume of the gas at a pressure of $50 \, cm \, Hg$ will be ........... $L$. (in $.25$)

In a $1 \ L$ flask,$N_2$ gas is at $100 \ kPa$ pressure,and in another $3 \ L$ flask,$O_2$ gas is at $320 \ kPa$ pressure. If both flasks are connected,what will be the resultant pressure in $kPa$?

The density of Neon will be highest at

At constant pressure,the volume of a gas is $300 \ mL$. If the temperature is changed from $27 \ ^oC$ to $-3 \ ^oC$,what will be the final volume in $mL$?
