Answer: 4 NH3 + 5O2 →4 NO +6 H2O From the reaction we can see that from 4 moles of ammonium we get 6 moles of water. M(NH3) =17 g/mol; M(H2O) = 18g/mol; The mass of water which is produced by the reaction we can find from the following proportion: 2.76 g of NH3 – 4 mol * 17 g/mol x g of H2O – 6 mol * 18g/mol then x = 6*18*2.79/(4*17) = 4.38 g The mass of water which is produced by the reaction is 4.38 g.
