A 25g piece of copper has a density of about 9g/cm3 what would the density be of a 100g piece of copper

Answer 1

The density would be 9g/cm^3, the same as the 25 g piece of copper. This is because density is based on mass and volume. The 100g piece of copper has 4 times the mass and thus would have 4 times the volume, and the same density as the 25 g piece.
