.to handle the sample, how would you determine the sample's density?
If you are sure that it's pure aluminum, you need to find the densityThe mass (or weight) can be determined on a simple balanceDepending on the sample's shape, you can determine the volume by simple water displacement (unless this is not allowed) If you can't touch it or handle it, you have a problemAbout the only other thing to do is some type of comparison to objects of known mass/volume.
