D = m/v (g/cm 3 ) Mass usually expressed in grams Volume usually expressed in cm 3 or liters, etc. Density = amount of matter per unit volume Density is the ratio of mass to volume If the volume stays the same and the mass increases... the density will increase If the mass stays the same and the volume increases... The density will decrease Key terms: density, area, volume, mass. Outcomes (5) Describe what density is. (6) Calculate density accurately using practical measurements. (7) Evaluate different methods that can be used to calculate density.
