the given rock is Cubic Zirconia.
given:
mass of the substance = 11.2g
volume of the substance =9cm³
Cubic Zirconia has a density -
5.5g/cm ³- 5.9 g/cm³
Here we will try to find the density of the given substance and compare it with the density of Cubic Zirconia .
we know that,
mass = density × volume
m=p×V
so,
density = mass/volume
on substituting value we get
density = 11.6/1.9
=6.1 g/cm³
which is approximately equal to 5.9 and therefore the rock is Cubic Zirconia.
