Density

What is the definition of density?

• The speed of light in a substance

• Amount of heat energy in a substance

• The force exerted by a substance

• Measure of mass per unit volume of a substance

How do you calculate density using mass and volume?

• Density = Mass * Volume

• Density = Mass - Volume

• Density = Mass / Volume

• Density = Volume / Mass
