How many moles of iron (Fe) will be produced from 6.20 moles of carbon monoxide (CO) reacting with excess iron (III) oxide (Fe2O3)?

Moles of Fe = 4.13

Given

6.2 moles of CO

Required

moles of Fe

Solution

The reaction coefficient shows the mole ratio of the reactants and products involved in the reaction equation

Reaction

Balanced equation

3CO + Fe₂O₃⇒ 2Fe + 3CO₂

From the equation, mol ratio of CO : Fe = 3 : 2, so mol Fe :

mol Fe = 2/3 x 6.2

mol Fe = 4.13
