pBenzene $$=xBenzene$$ pBenzene °pToluene $$=xToluene$$ pToluene ° For an ideal $$1$$:$$1$$ molar mixture of benzene and toluene, xBenzene $$=12$$  and  xToluene $$=12pToluene$$ $$=12$$  pToluene °$$=12$$×$$3.85kPa=1.925kPapBenzene$$ $$=12pBenzene$$ °$$=12$$×$$12.8kPa=6.4kPaThus$$, the vapour will contain a high percentage of benzene as the partial vapour pressure of benzene is higher as compared to that of toluene.
