Benzene and toluene form ideal  solution over the entire range of composition. The vapour pressure of pure benzene and naphthalene at `300K` are `50.71 mm Hg` and `32.06mm Hg`, respectively. Calculate the mole fraction of benzene in vapour phase if `80g` of benzene is mixed with `100g` of naphthalene.
