Molar volume $\left(V_m\right)$ of a van der Waals gas can be calculated by expressing the van der Waals equation as a cubic equation with $V_m$ as the variable. The ratio (in $\mathrm{mol}{\mathrm{dm}}^{-3}$ ) of the coefficient of $V_m^2$ to the coefficient of $V_m$ for a gas having van der Waals constants $a=6.0{\mathrm{dm}}^6\mathrm{atm}{\mathrm{mol}}^{-2}$ and $b=0.060{\mathrm{dm}}^3{\mathrm{mol}}^{-1}$ at 300 K and 300 atm is _____ . Use: Universal gas constant $(R)=0.082{\mathrm{dm}}^3\mathrm{atm}\mathrm{mol}{}^{-1}{\mathrm{K}}^{-1}$
