At$300 \mathrm{K}$, the vapour pressure of a solution containing$1$mole of$\mathrm{n}$-hexane and$3$moles of$\mathrm{n}$-heptane is$550 \mathrm{mm}$of$\mathrm{Hg}$. At the same temperature, if one more mole of$\mathrm{n}$-heptane is added to this solution, the vapour pressure of the solution increases by$10 \mathrm{mm}$of$\mathrm{Hg}$. What is the vapour pressure in$\mathrm{mmHg}$of$\mathrm{n}$- heptane in its pure state______?
