8. It is known that in the vapor-liquid equilibrium of the system benzene (1 component) - propanol (2 component) the mole fraction of the second component in the liquid phase is 0.06; in the system as a whole 0.14 and in the vapor phase 0.270. The mass of the system is 2 kg.
It is necessary to find:
1) the total number of moles in the system;
2) the number of moles in the vapor phase;
3) the mass of the vapor phase;
4) the mass of the liquid phase
