Answer
Given,
molecular mass of ammonium nitrate = 80
mass of nitrogen in 1 mole of ammonium nitrate (NH4NO3) is 2(14) = 28 g
percentage of nitrogen in ammonium nitrate = x 100 = 35%
mass of oxygen in 1 mole of ammonium nitrate (NH4NO3) is 3(16) = 48 g
percentage of oxygen in ammonium nitrate = x 100 = 60%
Hence, percentage of nitrogen is 35% and percentage of oxygen is 60%
