Question

If a rock sample has a mass of 1.17 g and a volume of 0.33 cm3, what type of rock is it? if a rock sample has a mass of 2.7 g and a volume of 1.1 cm3, what type of rock is it? if a rock sample has a mass of 11.2 g and a volume of 1.9 cm3, what type of rock is it?

The given rock is a diamond because its density ranges among 3.5 and 3.54 g/cm³.

### What is density?

Density is the mass of a specific material per unit volume. Density is commonly measured in grams per cubic centimetre. Water, for example, has a density of 1 gram per cubic centimetre, whereas Earth has a density of 5.51 grams per cubic centimetre.
• Density is also measured in kilograms per cubic metre (or metre-kilogram-second or SI units).
• Air has a density of 1.2 kilograms per cubic metre. Textbooks and handbooks list the densities of popular solids, liquids, and gases.
• Density provides an easy way to calculate a body’s mass from its volume and vice versa; a mass is proportional to the quantity multiplied by density (M = Vd), or the volume is equal to mass divided by the density. (V = M/d).
The formula for density is;
D = M/V,
where,
D is density,
M is mass ( = 1.17 g)
V is volume (0.33 cm³)
Substituting the values in the density formula;
Density = 1.17/0.33
Density = 3.54 g/cm³
As, diamond has a density that ranges between 3.5 & 3.54 g/cm3. As a result, the above rock is indeed a diamond.
