Calculate the amount of alumina substance obtained by combustion of 0.1 mol of aluminum.

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

4Al + 3O2 = 2Al2O3;

From two moles of aluminum, one mole of aluminum oxide is formed.

The amount of aluminum oxide substance will be:

N Al2O3 = N Al / 2 = 0.1 / 2 = 0.05 mol;
