If a rock sample has a mass of 11.2 g and a volume of 1.9 cm3, what type of rock is it a. diamond b. cubic zirconia c. common glass d. rudy

b. cubic Zirconia

Explanation:

The density of the rock sample that they are giving you is Mass divided by volume, this means 11.2g/1.9cm3, this means the density of the given rock is 5.89 g/cm3, the densities of the rocks you are given in the choices are:

Diamond: 3.5 g/cm3 - 3.53 g/cm3

Cubic Zarconia:5.5g/cm3 - 5.9 g/cm3

Common glass: 2.4 g/cm3 - 2.8g/cm3

Ruby: 4.02 g/cm3 - 4.3 g/cm3

Which means that the one that is closer to the rock sample that you have is cubic Zirconia.
