Question

Which of the following best defines density?

A.
A measure of the volume of a given substance

B.
A number between 0 and 1 that defines how thick a substance is

C.
A measure of how much mass a given volume of a substance will have

D.
A measure of the mass of a given substance

Answer 1

Density is mass per unit volume, therefore the correct answer is C. A measure of how much mass a given volume of a substance will have

Answer 2

Density = mass/volume

Explanation:

The mass per unit volume of a given substance is called its density. It can be represented by d or ρ. Mathematically, it is given by :

density=mass/volume

The SI unit of mass is kg and the SI unit of volume is m³. So, the SI unit of density is kg/m³.

So, the statement that defines density is "A measure of how much mass a given volume of a substance will have". Hence, the correct option is (c).
