A large piece of jewelry has a mass of 132.6 g.

A graduated cylinder initially contains 48.6 mL water. When the jewelry is submerged in the graduated cylinder, the total volume increases to 61.2 mL.

Given that 1 mL = 1 cm3, and the density of copper is 9.0 g/cm3, the density of gold is 19.3 g/cm3, the density of silver is 10.5 g/cm3, and the density of aluminum is 2.7 g/cm3, what substance is the jewelry likely to be?

List the following in order from LEAST DENSE to MOST DENSE. Use the information in Table 1.4 on page 34, which gives the densities of common substances:

Olive oil, copper, carbon dioxide (gas), water, mercury
