Density

What is density?

• The atoms inside a solid, liquid or gas.

• A measure of the amount of matter in an object.

• The quantity of mass contained inside a unit volume.

• A measure if something is heavier than a liquid.

Which is the correct equation for density?

• Density =

  Weight / Volume

• Density =

  Weight / Mass

• Density =

  Volume / Mass

• Density =
