For a real gas at $25^{\circ} \mathrm{C}$ temperature and high pressure ( 99 bar ) the value of compressibility factor is 2 , so the value of Vander Waal's constant 'b' should be $\_\_\_\_$ $\times 10^{-2} \mathrm{~L} \mathrm{~mol}^{-1}$ (Nearest integer) (Given $\mathrm{R}=0.083 \mathrm{~L}$ bar $\mathrm{K}^{-1} \mathrm{~mol}^{-1}$ )
