Question

An artist creates a solid sculpture made from 7.10 kg of tin. She wishes to create an identical sculpture, using the same mold used to make the original, out of solid lead. What is the mass (in kg) of the lead sculpture? (The density of tin is 7.26 ✕ 103 kg/m3, and that of lead is 11.30 ✕ 103 kg/m3.)

Answer 1

Answer:

7.10(11.30/7.26) = 11.05 kg

Explanation:

dividing by the density of tin gives the volume of the sculpture

multiplying that volume by the density of lead gives the lead mass required.
