Question

ammonia nh3 and oxygen can be reacted together in the presence of a catalyst to form only nitrogen monoxide and water. if 2.67 mol of ammonia is reacted with excess oxygen, what mass of water would be produced?

Answer 1

The balanced reaction equation:
4NH₃ + 5O₂ → 4NO + 6H₂O
Molar ratio of ammonia to water:
4 : 6 = 2 : 3
Moles of ammonia = 2.67
Moles of water = 2.67 x 3/2
Moles of water = 4.0

Mass of water = 4 x 18
= 72 grams
