Ammonia (NH3) is widely used as a fertilizer
and in many household cleaners. How much

Answer:

Mass of ammonia produced = 40.29 g

Explanation:

Given data:

Number of moles of H₂ = 3.55 mol

Mass of ammonia produced = ?

Solution:

Chemical equation:

3H₂ + N₂     →      2NH₃

Now we will compare the moles of ammonia with hydrogen

                H₂          :          NH₃

                 3           :            2

               3.55       :        2/3×3.55 = 2.37 mol

Mass of ammonia:

Mass = number of moles × molar mass

Mass = 2.37 mol ×  17 g/mol

Mass = 40.29 g
