"Equal volumes of all gases at the same temperature and pressure contain equal number of particles." This statement is a direct consequence of

For an ideal gas,the compressibility factor $(Z)$ is

Calculate the pressure of $1.5 \ mol$ of gas having volume $3 \ dm^3$ at $300 \ K$ $(R=0.0821 \ dm^3 \ atm \ K^{-1} \ mol^{-1})$. (in $atm$)

$A$ weather balloon filled with hydrogen at $1 \, atm$ and $27 \, ^oC$ has a volume equal to $12000 \, L$. On ascending,it reaches a place where the temperature is $-23 \, ^oC$ and the pressure is $0.5 \, atm$. The volume of the balloon is .............. $L$.

The $S.I.$ unit of the gas constant $R$ is:

The variation of volume of an ideal gas with its number of moles $(n)$ is obtained as a graph at $300 \ K$ and $1 \ atm$ pressure. What is the slope of the graph?
