Ammonia is made by the reaction of nitrogen and hydrogen under high temperature and pressure. In order to prepare the feed gas for the reactor, pure hydrogen is mixed with air (79% N2 and 21% O2) and the oxygen removed by water formation. The resulting mixture, after compression and drying, is to have the proper stoichiometric ratio of H2/N2 for NH3 formation. On the basis of 100 moles of air, how many moles of water would condense from the mixture of H2, N2, and H2O when the gases are cooled from the combustion temperature to 320 and 2 atm pressure?
