The vapour pressures of two volatile liquids A and B at $\displaystyle 25^{\circ} \mathrm{C}$ are $\displaystyle 50$ Torr and $\displaystyle 100$ Torr, respectively. If the liquid mixture contains $\displaystyle 0.3$ mole fraction of A , then the mole fraction of liquid $\displaystyle B$ in the vapour phase is $\displaystyle \frac{x}{17}$. The value of $\displaystyle x$ is \_\_\_\_.
