Density

Density = a measure how much matter is packed into a given area. It is a property of a substance.

The closer the molecules are, the greater the density.

Density tells us how many grams of matter there are per a unit of volume.

Density calculations

Common units:

• grams per cubic centimeter (g/cm3) 
• grams per milliliter (g/mL)
