Using the following balanced equation, how many moles of Iron (II) oxide is produced if you start with 3 moles of oxygen? 2 Fe + O2 → 2 FeO

Answer 1

Hello, Tolani,

2 Fe + O2 → 2 FeO

The balanced equation says we'll get 2 moles FeO for every 1 mole of O₂. That's a molar ratio of (2FeO/1O₂) .

Starting with 3 moles of O₂, and assuming sufficient Fe is present, we would expect :

(3 moles O₂)*(2 moles FeO/1 mole O₂) = 6 moles FeO
