Calculate the mass of zinc in the penny.

You weigh a graduated cylinder to be 58.248 grams when it is empty. You then add some unknown liquid and determine the volume of liquid to be 11.31 mL based on the marking on the graduated cylinder. You then weigh it again to find a total mass of 68.466 grams. What is the density of the unknown substance, based on these measurements? Give you answer in decimal format.

A student wondered if their necklace was real silver. They weighed the necklace and found it was 3.17 g. Then, they filled a graduated cylinder with 25.0 mL of water and submerged the necklace, to find a new volume of 25.3 mL. Is the necklace real silver? Density of silver = 10.49 g/mL
