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)

Solution
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).
