Answer:
For 8 moles of iron 6 moles of oxygen are required.
Explanation:
Given data:
Number of moles of oxygen needed = ?
Number of moles of Fe = 8 mol
Solution:
Chemical equation:
4Fe + 3O₂ → 2Fe₂O₃
Now we will compare the moles of iron and oxygen from balance chemical equation.
Fe : O₂
4 : 3
8 : 3/4×8 = 6
So for 8 moles of iron 6 moles of oxygen are required.
