Calculate how much aluminum is required to obtain 1 mol of aluminum oxide.

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

4Al + 3O2 = 2Al2O3;

There are two metal atoms in an aluminum oxide molecule. Therefore, from two moles of aluminum, one mole of its oxide is formed.

To obtain 1 mole of oxide, 2 moles of metal are needed.

N Al = N Al2O3 x 2 = 1 x 2 = 2 mol;

M Al = 27 grams / mol;

m Al = 27 x 2 = 54 grams;

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
