Question

If you are sure that a sample of material is aluminum but have no measuring instruments AND are not allowed to handle the sample, how would you determine the sample’s density?

Answer 1

The density of aluminum is always 2.7 g/cm3

Answer 2

Find the density in a reference book.

Step-by-step explanation:

Given that you are not allowed to handle the sample, then you cannot perform any kind of laboratory test. But you know that the material is aluminium, so you can go to a reference book and look up the density there, which is 2.7 g/mL.
