Answer:
7.5 moles of hydrogen is required
Explanation:
Given data:
Number of moles of H₂ needed = ?
Number of moles of NH₃ = 5 mol
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of ammonia and hydrogen.
NH₃ : H₂
2 : 3
5 : 3/2×5 = 7.5 mol
Thus, 7.5 moles of hydrogen is required.
