All you have to do is weigh it. Then take the mass and divide by the atomic mass of aluminum which is 26.98 grams per mole. This will give you the number of moles. Then take the number of moles and multiply that by Avogadro's number (6.02 x 10 ^23) and you will have the number of atoms.

It's very simple experiment.
Weigh the aluminum foil in an electronic balance.
You know the atomic mass of aluminum, and the Avogadro's number.
Avogadro's number (6.022 x 10^22) of atoms are present in 1 mol aluminum - use dimensional analysis to calculate the number of atoms in the given mass of aluminum foil.
Hope it helps

Weigh it a precisely and accurately as you can. Use the atomic mass of aluminum, 26.98 grams/mole along with avogadro's number, 6.022 X10^23 atoms/mole. So with the weight of the piece of foil, you can get moles from the atomic mass, then atoms from avogadro's number.

I made a hat that I wear all the time out of aluminum foil, the government can't read my thoughts now.

you find the mass of the aluminum by weighing it.
X g * (1 mol/ 26.9815g) * (6.02 x 10^23 atoms/ 1 mol)= X atoms

the easiest way is just to weight it and then divide by the atomic weight. then multiply by avagadroos number

how about you use a scale and the molecular mass?
