Well, aluminum is an element, so none. However, aluminum does oxidize, and some quantity of oxygen might be derived if you will provide the surface area of the aluminum being oxidized, and the conditions, which would estimate a rate of oxidation without actually giving you any meaningful number. Aluminum oxide--the oxidate on the surface of oxidized aluminum--is Al2O3, or 2 parts Al to 3 parts O.
There are three oxygen atoms present in a formula unit of Aluminum Hydroxide (Al(OH)3).
1 formula unit of aluminum sulfate has the formula Al2(SO4)3. So there are 2 atoms of aluminum, 3 atoms of sulfur and 12 atoms of oxygen in 1 formula unit of aluminum sulfate. There are no molecules of aluminum sulfate. They are called formula units.
The formula unit of aluminum nitrate is Al(NO3)3. This shows that the formula unit contains 1 aluminum atom, 3 nitrogen atoms, and 9 oxygen atoms for a total of 13 atoms.
Al2(SO4)3 So: 2x Aluminium 3x Sulphur 12x Oxygen
The formula unit for aluminum nitrate has the formula Al(NO3)3. Subscripts within parentheses are multiplied by the subscript after the parentheses. Therefore, this formula unit contains nine oxygen atoms, three nitrogen atoms, and one aluminum atom for a total of 13 atoms.

The formula unit for aluminum oxide is usually considered to be Al2O3 (even though the bonding may vary in different allotropes). Using this formula unit, each one contains 5 total atoms, found by adding all the subscripts in the formula.
Aluminum dichromate has the formula unit of Al2(Cr2O7)3. This means there are two aluminum, six chromate and 21 oxygen atoms present for a total of 29 atoms.
There are 4 atoms of aluminum in 2Al2O3. Each formula unit of Al2O3 contains 2 atoms of aluminum. Therefore, when we have 2 formula units (2Al2O3), we have a total of 4 aluminum atoms.
There are a total of three oxygen atoms in the formula unit of calcium carbonate, CaCO3.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
There are two oxygen atoms in one unit of the compound Ba(OH)2.
