In an ideal monoatomic gas, the speed of sound is given by $\sqrt{\frac{5RT}{3M}}$. If the speed of sound in argon at $25^\circ\mathrm{C}$ is $1245\ \mathrm{km\ h^{-1}}$, the root mean square velocity in $\mathrm{ms^{-1}}$ is ______. 18. The relationship between the van der Waals ‘b’ coefficient of $\mathrm{N}_2$ and $\mathrm{O}_2$ is
(a)$b(\mathrm{N}_2)=b(\mathrm{O}_2)=0$
(b)$b(\mathrm{N}_2)=b(\mathrm{O}_2)\neq 0$
(c)$b(\mathrm{N}_2)>b(\mathrm{O}_2)$
(d)$b(\mathrm{N}_2)<b(\mathrm{O}_2)$
