Question

N₂ + 3H₂ → 2NH₃

(The atomic mass of nitrogen is 14, and that of hydrogen is 1)

1 mole of nitrogen (______ g) +

3 moles of hydrogen (______ g) →

2 moles of ammonia (______ g)

Answer 1

N₂ + 3H₂ → 2NH₃

• 1 mole of N₂ = 28 g
• 3 moles of H₂ = 6 g
• 2 moles of NH₃ = 34 g
  ⇒ 1 mole of nitrogen (28 g) + 3 moles of hydrogen (6 g) → 2 moles of Ammonia (34 g).
