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.
