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

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
