Oxygen density in air
WebThe density (ρ) of oxygen (O 2) 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. Many species require molecular ... WebAnd water vapor molecules are lighter than both nitrogen and oxygen. In other words, humid air is going to have less heavy nitrogen and oxygen -- and lighter hydrogen and oxygen -- in its place. Remember that they have …
