The following set of reactions can be used to produce nitric acid, HNO3. Calculate the mass of nitric acid produced from the reaction of 15.5 kg of nitrogen gas with excess hydrogen gas. Each reaction in turn has an excess of the second reactant added.
N2(g) + 3 H2(g) ? 2 NH3(g)
4 NH3(g) + 5 O2(g) ? 4 NO(g) + 6 H2O(g) 2 NO(g) + O2(g) ? 2 NO2(g)
3 NO2(g) + H2O(l) ? 2 HNO3(aq) + NO(g)
