Question

15. You find a ring with a mass of 107g. You fill a graduated cylinder up with 10mL of water

and put the ring into the cylinder. The water rises up to the 15mL mark. What is the ring made
of?
A. Diamond
B. Platinum
C. Gold
D. Copper

Answer 1

The ring is most likely made of gold based on its density.

Step-by-step explanation:

The mass of the ring is given as 107g and the water level in the graduated cylinder rises from 10mL to 15mL after the ring is added. We can use the concept of density to determine the material the ring is made of. Density is defined as mass divided by volume. By calculating the density of the ring, we can compare it to the densities of different materials to determine its composition. In this case, the density of the ring is 10.7g/mL. Comparing this to the known densities of various materials, we find that the density of gold is approximately 19.3g/mL, making it the closest match to the density of the ring. Therefore, the ring is most likely made of gold.
