In terms of density, how does lead compare to tin?

• A. Lead is denser than tin.
• B. Tin is denser than lead.
• C. They have equal density.
• D. Lead and tin have no defined densities.

Answer: (A)

Density is the amount of mass packed into a given volume. A metal with heavier atoms and a structure that packs more mass into each cubic centimeter will be denser. Lead has a density of about 11.34 g/cm^3 at room temperature, while tin is about 7.31 g/cm^3. That means, for the same volume, lead weighs more than tin, so it is denser. So the best answer is that lead is denser than tin. The other ideas don’t fit because densities are defined properties at a given temperature, and tin is not denser than lead, nor are they equal in density.
