Two flasks I and II shown below are connected by a valve of negligible volume.
When the valve is opened, the final pressure of the system in bar is $\displaystyle x \times 10^{-2}$. The value of $\displaystyle x$ is \_\_\_\_. (Integer answer)
[Assume - Ideal gas; $\displaystyle 1 \mathrm{bar}=10^5 \mathrm{~Pa} ;$ Molar mass of $\displaystyle \mathrm{N}_2=28.0 \mathrm{~g} \mathrm{~mol}^{-1} ; \mathrm{R}=8.31 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$ ]
