Answer:
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
Explanation:
Given data:
Number of moles of hydrogen react = 4.0 mol
Number of moles of ammonia produced = ?
Solution:
Chemical equation:
N₂ + 3H₂   →    2NH₃
Now we will compare the moles of hydrogen and ammonia from balance chemical equation.
             H₂        :        NH₃
              3         :         2
              4         :        2/3×4 = 2.67 mol
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
