Moles of Fe2O3 used : 3.83

Further explanation

Given

11.5 moles of CO2

Required

moles of Fe2O3

Solution

Reaction

Fe2O3 + 3CO ⇒2Fe + 3CO2

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
