Pb 11.3437
Zn 7.14
Fe 8.39
Sn 7.28

You are given a metal block with a mass of 62.44g and a mass of 7cm3. What is the identity of your block? How did you know?

Cu 8.92

Explanation:

The formula for density is mass/volume. If you were to divide 62.44 by 7, you would get 8.92. Since copper is the only metal in this table that has a density of 8.92, that is the answer.
