Which of the following laws gives the relation between volume and temperature?

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

$A$ gas occupies a volume of $0.35 \ dm^3$ at $290 \ K$ and $2 \ atm$ pressure. Calculate the volume of the gas at $STP$. (in $dm^3$)

What is the molar volume of an ideal gas at $STP$ (or $NTP$) and $SATP$?

Air entering the lungs ends up in tiny sacs called alveoli. It is from the alveoli that oxygen diffuses into the blood. The average radius of the alveoli is $0.0050 \ cm$ and the air inside contains $14$ per cent oxygen. Assuming that the pressure in the alveoli is $1.0 \ atm$ and the temperature is $37 \ ^oC$,calculate the number of oxygen molecules in one of the alveoli.

At $0\, ^\circ C$ and $1\, atm$ pressure,a gas occupies $100\, cc$. If the pressure is increased to $1.5$-times and temperature is increased by one-third of its absolute temperature,then the final volume of the gas will be .............. $cc$.
