Nitric oxide is made from the oxidation of ammonia.What mass of nitric oxide can be made from the reaction of 8.00 g NH₃ with 17.0 g O₂? 4 NH₃(g)+ 5 O₂(g)→ 4 NO(g)+ 6 H₂O(g)

First, calculate the molar mass of NH3 and O2. NH3 = 14.01 (N) + 3*1.01 (H) = 17.03 g/mol, O2 = 2*16.00 = 32.00 g/mol. Then, find the moles of NH3 and O2: 8.00 g NH3 / 17.03 g/mol = 0.470 mol NH3, 17.0 g O2 / 32.00 g/mol = 0.531 mol O2. The reaction ratio is 4 NH3 : 5 O2, so NH3 is the limiting reagent. The moles of NO produced from NH3 are in a 1:1 ratio, so 0.470 mol NH3 produces 0.470 mol NO. The molar mass of NO = 14.01 (N) + 16.00 (O) = 30.01 g/mol. Therefore, the mass of NO = 0.470 mol * 30.01 g/mol = 14.1 g.
