Students were asked to identify an unknown cube of metal based on the property of density.

What is the identity of the metal?
a Lead
b Copper
c Aluminum
d Iron
It is not possible to determine the identity of the metal based solely on its density. Additional information such as the weight, color, and other observable properties would be necessary to make a more accurate identification.
To determine the identity of the metal, we need to compare the density of the unknown cube to the known densities of different metals. Here are the densities of the metals mentioned:
a) Lead: 11.34 g/cm3
b) Copper: 8.96 g/cm3
c) Aluminum: 2.70 g/cm3
d) Iron: 7.87 g/cm3
Measure the dimensions of the cube and calculate its density by dividing its mass by its volume. Then compare the calculated density to the densities listed above. Based on the comparison, you can determine the identity of the metal.
