Question

Ammonia (NH3) is widely used as a fertilizer

and in many household cleaners. How much
ammonia is produced when 3.55 mol of hydrogen gas react with an excess of nitrogen

Answer 1

Mass of ammonia produced = 40.29 g

Step-by-step 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
