How many moles of Fe2O3 will be produced when 12.2 moles of O2 react with Fe?

Explanation:

When iron rusts in air, iron (III) oxide is produced. How many moles of oxygen react with 12.9 mol of iron in the rusting reaction? 4Fe(s)+3O2(g)→2Fe2O3(s)?

Chemistry  The Mole

9.675 mol of oxygen gas.

Explanation:

We have the balanced equation:

4Fe(s)+3O2(g)→2Fe2O3(s)

And so, 4 moles of iron react with 3 moles of oxygen, and therefore, 12.9 mol of iron would react with:

12.9mol Fe⋅3 mol O24mol Fe=9.675 mol O2
