Question

How many moles of iron can be made from 6 moles H2?

Fe2O3(s) + 3H2(g) → 2Fe(s) + 3H2O(l)

Answer 1

Number of moles of Fe formed = 4 mol

Step-by-step explanation:

Given data:

Number of moles of H₂ = 6 mol

Number of moles of Fe formed = ?

Solution:

Chemical equation:

F₂O₃ + 3H₂ → 2Fe + 3H₂O

Now we will compare the moles of H₂ with Fe from balance chemical equation.

H₂ : Fe

3 : 2

6 : 2/3×6 = 4 mol

From 6 moles of H₂ 4 moles of Fe are produced.
