Moles of Fe2O3 used : 3.83
<h3>Further explanation</h3>
Given
11.5 moles of CO2
Required
moles of Fe2O3
Solution
Reaction
<em>Fe2O3 + 3CO ⇒2Fe + 3CO2 </em>
The reaction coefficient shows the mole ratio of the reacting compound (reactants or products)
From the equation, mol ratio of Fe2O3 : CO2 = 1 : 3, so mol Fe2O3 :
= 1/3 x moles CO2
= 1/3 x 11.5
= 3.83 moles
