4. a gas containing equal parts methane, ethane and ammonia flows at a constant rate through a laboratory water- based absorption unit, which absorbs 96% of the ammonia and retains all the water. no methane or ethane is absorbed and no water evaporates. initially there was 5 l of water in the absorber, at the end of 4 hours the liquid mass is 5.25 kg. calculate the molar flowrate of the gas stream into the absorber, and the mole fraction of ammonia in the exit gas stream
