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.

Question
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.
