At $\displaystyle 1990$ K and $\displaystyle 1$ atm pressure, there are equal number of $\displaystyle \mathrm{Cl}_2$ molecules and Cl atoms in the reaction mixture. The value of $\displaystyle \mathrm{K}_{\mathrm{p}}$ for the reaction $\displaystyle \mathrm{Cl}_{2(\mathrm{~g})} \rightleftharpoons 2 \mathrm{Cl}_{(\mathrm{g})}$ under the above conditions is $\displaystyle x \times 10^{-1}$. The value of $\displaystyle x$ is \_\_\_\_. (Rounded off to the nearest integer)
