On mixing ,heptane and octane form an ideal solution.At 373K,the vapour pressures of the two liquid components (heptane and octane) are 105kPa and 45kPa respectively.Vapour pressure of the solution obtained by mixing 25g of heptane and 35g of octane will be (molar mass of heptane=100g $mol^{-1}$ and octane=114g$mol^{-1}$)
