2. Definition A measure of the amount of matter in a given space
It is a characteristic property
It is equal to the mass of a mL or a cm³ of a substance
It is the mass/volume ratio

4. Symbol = ρ (Greek letter rho)
Units = kg/m³ or g/cm³ or g/mL
Equation
Density = mass/volume
ρ = m/V

5. Example
If a sample of 20 mL of acetone has a mass of 15.8 g, what is the density of the acetone in g/mL? ρ = m/V where m = 15.8 g and V = 20 mL ρ = 15.8 g / 20 mL ρ = 0.79 g/mL The density of acetone is 0.79 g/mL
