Moles Fe₂O₃ produced : 1.16 moles
<h3>Further explanation</h3>
Given
2.32 moles of iron
Required
moles of Fe2O3
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the reacting compounds (reactants and products)
Reaction
4 Fe + 3 O₂ ⇒ 2 Fe₂O₃
From the equation, mol ratio Fe : mol Fe₂O₃ = 4 : 2, so mol Fe₂O₃ :
= 2/4 x mol Fe
= 2/4 x 2.32
= 1.16 moles
