nordsb [41]

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.
