Density: Accuracy and Precision
GCC CHM 151LL: density : Accuracy , and Precision GCC, 2008 page 1 of 5 density : Accuracy and Precision Introduction: density is a measure of a substance s mass-to-volume ratio. For liquids and solids, density is usually expressed in units of g/mL or g/cm3; these are equivalent since 1 mL is exactly equal to 1 cm3. density is an intensive property meaning that a substance s density will be the same regardless of the size of a sample. For example, steel has a density of g/cm3 whether you have a tiny steel ball bearing or a large steel beam. The mass and volume of each piece will be different, but the mass-to-volume ratio is the same! In general, different substances have different densities even if they occupy the same volume or have the same mass.
