the denisty of copper is 8.96g/cm3. A sample of a metal mass of 40.0g and a volume of 6.0 cm3 what can you determine about the sample?

The sample's density, 6.67 g/cm^3, is less than that of copper. Therefore it is not copper. It isn't any other heavier metal or alloy than copper, either.

Wow how did you figure that out?
