The reacting amount of oxygen is 7.3 grams. First, we construct a reaction equation. This is: 4NH₃ + 5O₂ → 4NO + 6H₂O Next, we find the moles of oxygen gas present, this is: Moles = mass / Mr Moles = 7.3 / 32 Moles = 0.23 The molar ratio of nitric oxide to oxygen is 4 : 5; using this, we find the moles of nitric oxide produced to be: 0.23 * 4/5 0.18 moles of nitric oxide We find the mass using the same formula as above: mass = 0.18 * 30 mass = 5.4 g 5.4 grams of nitric oxide will be produced.
