    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 x×10−2x \times10^{- 2}. The value of xx is (Integer answer) [Assume-Ideal gas; 1bar=105 Pa1bar =10^{5}\text{ }Pa; Molar mass of  N2=28.0 g mol−1;R=8.31 J mol−1 K−1]\left. \ N_{2}= 28.0\text{ }g{\text{ }mol}^{- 1};R = 8.31\text{ }J{\text{ }mol}^{- 1}{\text{ }K}^{- 1} \right\rbrack
