Question

The volume of a solution was measured in a gradulated cylinder, and the volume is unknown. The water level is measured is 60.75 mL. The beginning water level was 24.00. The mass of the solution is 110.25 grams. What is the volume of the solution, and what is the density of this solution?

Answer 1

To find the density of the jewelry, divide the mass of the jewelry by its volume. The density of the jewelry is 10.57 g/mL. The jewelry is likely made of gold based on its density.

Step-by-step explanation:

To find the density of the jewelry, we need to use the formula density = mass/volume. The initial volume of water in the graduated cylinder is 48.6 mL and it increases to 61.2 mL when the jewelry is submerged. The change in volume is 61.2 mL - 48.6 mL = 12.6 mL. So, the volume of the jewelry is 12.6 mL. Now, we can calculate the density using the given mass (132.6 g) and volume (12.6 mL): density = 132.6 g / 12.6 mL = 10.57 g/mL.

To determine the substance likely to be the jewelry, we can compare its density with known densities of substances. Based on the calculated density of 10.57 g/mL, it is most likely that the jewelry is made of gold. Gold has a density of approximately 19.3 g/mL, which is close to the obtained density.
