The composition of the raw material is 60 mol% benzene, 40 mol% toluene, and the flow rate is 100 kmol/h. The temperature and pressure conditions of the raw material solution are 100degrees Celsius and 350 kPa. In this case, when the operating conditions of the flash drum are 100 degrees Celsius and 120 kPa,

1) Calculate the mole fraction of steam on the flash drum to the fourth decimal place.

2)Calculate the molar flow of steam and liquid flow to the second decimal place in kmol/h.

3)Estimate the mole fraction of each component in the vapor phase and liquid phase to the fourth decimal place.

However, use the Antoine vapor pressure estimation formula based on the temperature of the pure ingredients given below.
