Question

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.

(a) Determine the density of this piece of jewelry.
(b) Assuming that the jewelry is made from only one suvstance, what substance is it likely to be? Explain

Answer 1

The density of the jewelry piece is 10.57 g/mL. The jewelry is likely made of a dense material like gold, platinum, or lead.

Step-by-step explanation:

First, we can calculate the volume of the jewelry piece by subtracting the initial volume of the water from the final volume when the jewelry is submerged. The volume of the jewelry is 61.2 mL - 48.6 mL = 12.6 mL.

To determine the density, we use the formula:

Density (p) = mass (m) / volume (V)

Substituting the given values, we have:

Density = 132.6 g / 12.6 mL = 10.57 g/mL

For part (b), we can compare the density of the jewelry to the known densities of different materials. Since the density of the jewelry is 10.57 g/mL, it is likely to be made of a dense material like gold, platinum, or lead, rather than a less dense material like aluminum or plastic.
