On mixing , heptane and octane form an ideal solution . At 373 K  , the vapour pressures of the two liquid components (heptanes and octane ) are 105 `kP_(a)` and `45kP_(a)` respectively . Vapour pressure of the solution obtained by mixture `25.0` g of heptane and 25  g of octane will be : (Molar mass of heptane `-100 g mol^(-1)` and of octane = `114 g mol^(-1)` )
