Calculate moles of oxygen needed to react with 0.128 mol of ammonia: 5 mol O2 nW = 0.128 mol NH3 × = 0.160 mol 4 mol NH3 Since the required amount of oxygen is more than the amopunt available to react, oxygen is limiting and ammonia is in excess. The problem can also be solved by calculating moles o ...
