441.5 ml of heptane (C7H16) is mixed with 811.4 ml of octane (C8H|8) to form an ideal solution at 30°C. The densities of heptane and octane at 30°C are 0.6795 and 0.7025 g/ml respectively. At 30°C,the vapour pressure of heptane is 0.121 atm and vapour pressures of octane is o.o41atm.What is the total vapour pressure of the solution ?What is the mole fration of heptane in vapour above this solution?
