Question

How many moles of H 2 will I need to make 5 moles of NH3?
12 SSO

Answer 1

7.5 moles of hydrogen is required

Step-by-step 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.
