Being Dense

Density
Density is the mass of an object divided by the volume.

The simple equation is Density= Mass/Volume or D=M/V

How dense an object or substance is can tell you if it will float or sink in a fluid or if it's just heavier than another substance. Density also shows how close a substances particles are together, leading to solids usually being more dense than their fluid states. Density can also help identify pure substances if known accepted values are compared.
