how to find the thickness and/or the layers of atom that an aluminum paper has.

Thank you In advance

Do you actually have a problem in front of you?

The usual way to find thickness is to find out the mass, divide by the density and then divide by the area.



To find the layers of atom you'd then divide by the atomic radius (and since atomic radii are usually measured in pm you'll get a lot of them



Note all units should be SI

It wouldn't be a problem IF we knew how to do it; the teacher told us to search in the internet, in books or ask a friend to find the answer. In short I don't really have to do the exercise, but due to my curiosity, i'm trying to do it . Thank you for the answer!! =)

I should point out that I made the assumption that the aluminium is spread out uniformly, ie: all parts are equally thick. This is usually the case and a safe assumption to make unless told otherwise

It's got a square-shaped figure, so i'm assuming that your answer's correct thanks.
