please explain the eqution

3) A sealed container contains both vapor and liquid water in equilibrium at 150kPa. If the average internal energy of all the water in the container is 1,900[kJ/kg ], what fraction of the total mass is in the vapor phase? (Hint: Combine a material balance and an energy balance equation. Assume a basis for the total mass of water.)
