Question

How many moles are required to react with 4.5 moles of H2?

N2 + 3 H2 ------> 2 NH3

Answer 1

1.5 mol

Step-by-step explanation:

Given data:

Number of moles of H₂ = 4.5 mol

Number of moles of N₂ = ?

Solution:

Chemical equation:

N₂ + 3H₂ → 2NH₃

Now we will compare the moles of hydrogen and nitrogen.

H₂ : N₂

3 : 1

4.5 : 1/3×4.5 = 1.5 mol

Thus, 1.5 moles of nitrogen are required to react with hydrogen.
