How much oxygen (mol) is required to burn 8 moles of aluminum?

The combustion reaction of aluminum is described by the following chemical reaction equation:

4Al + 3O2 = 2Al2O3;

The reaction with 4 moles of aluminum requires 3 moles of oxygen. This produces two moles of aluminum oxide.

The required amount of oxygen will be:

N O2 = 8 x 3/4 = 6 mol;
