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