please answer only part (a) and DO NOT use stripping formula

only using the general material balance methods please answer only part (a) and DO NOT use stripping formula

A liquid feed of 100kmol/h at the boiling point contains 3.3mol% ethanol and 96.7mol% water and enters the top tray of a stripping tower. 24.2kmol/h of saturated steam is injected directly into liquid in the bottom of the tower. The overhead vapor which is withdrawn contains 99% of alcohol in the feed. Assume equimolar overflow for this problem. Equilibrium data for mole fraction of alcohol at 101.32kPa abs pressure are as follows. (a) Calculate the flow rates and compositions of the overhead vapor and bottoms. (b) Calculate the number of theoretical stages needed
