WebMay 6, 2024 · Density is a measure of the amount of mass contained in a unit of volume. The general trend is that most gases are less dense than liquids, which are in turn less dense than solids, but there are numerous exceptions. For this reason, the table lists density from lowest to highest and includes the state of matter. WebThe density (ρ) of oxygen (O2) is 1.428 g/L at a standard temperature and pressure. The molar mass of an oxygen (O) atom is 15.9996 grams per mole. Density is defined by the mass-to-volume ratio of a substance and has units of [g/L], [kg/m3] or [lb/ft3]. Oxygen is a diatomic gas with a 180-degree bond angle.
