True or False "Density has no units?"?

Answer 1

False, BUT....

It depends on what sort of "density" you are using. Density is simply the mass divided by the volume, which will have units of m/V.

However a special type of density is known as relative density, also called specific gravity. This value is dimensionless. Relative density or specific gravity is determined by setting the value of of some standard, most often water but sometimes air, to one. The relative density then is the comparison of this standard to the substance being measured. Specific gravity is very commonly used by geologists and mineralogists to record the relative density of minerals.

Since you are asking this question under Earth Science, it seems relevant to point out that this relative density terminology exists and truly has no units.

Answer 2

False. Density is mass per volume, both of which have units and neither of which cancels out the other.

Answer 3

This is true. Being dense has no units but is an effect of getting other people to do your homework while you float along in life's little stream. Trouble is eventually you'll sink as your density increases in inverse proportion to your lack of knowledge.

Answer 4

False. Density is mass per unit volume, often expressed in g/cc or lb/cu ft, etc.

Answer 5

False.

Answer 6

False.

Answer 7

False.

Density is mass per unit volume.

The SI derived unit for density is:
kg/m^3
