Final answer:
The density of the jewelry is 10.57 g/cm³. The jewelry is likely made of a dense substance such as gold, platinum, or tungsten.
Step-by-step explanation:
To calculate the density of the jewelry, we divide the mass of the jewelry by the change in volume of water in the graduated cylinder.
The mass of the jewelry is 132.6 g and the change in volume is 61.2 mL - 48.6 mL = 12.6 mL. We convert mL to cm³ by multiplying by 1 cm³/1 mL. Therefore, the change in volume is 12.6 cm³. Dividing the mass by the volume, we get the density of the jewelry:
Density = 132.6 g / 12.6 cm³ = 10.57 g/cm³.
To determine what substance the jewelry is likely made of, we can compare the density of the jewelry to the densities of known substances. Based on the density of 10.57 g/cm³, the jewelry is likely made of a dense substance such as gold, platinum, or tungsten, which have similar densities.
