Aluminum (Al) foil doesn't have a "molecular formula" because it's all aluminum. The foil is made from a solid block of refined aluminum (all Al) and rolled and rerolled to compress it and form the foil. One way to evaluate aluminum foil might be to look at the metallic crystal structure that results at the end of the rolling process through which the foil is manufactured. But that requires another question.
