Answer:
5 moles of ammonia would be formed.
Explanation:
Given data:
Moles of NH₃ formed = ?
Moles of H₂ react = 7.5 mol
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of ammonia with hydrogen.
H₂ : NH₃
3 : 2
7.5 : 2/3×7.5 = 5
5 moles of ammonia would be formed from 7.5 moles of hydrogen.
