Question

My question is how many moles of oxygen react with 2.4 moles of iron

Answer 1

1.8 mol O₂

Procedure

Considering the following chemical reaction:

4Fe + 3O₂ → 2Fe₂O₃

To solve the exercise we will assume that oxygen is in excess and iron is the limiting reaction.

Based on this and the stoichiometry of the reaction we have the following equation:

`2.4\text{ mol Fe}\frac{3\text{ mol O}_2}{4\text{ mol Fe}}=1.8\text{ mol O}_2`
