WebNov 20, 2024 · The density gradient will be very small, but will depend on the strength of gravity, the pressure, the temperature, and the mass of the gas molecules. The range of energies for O2 and CO2 at a given temperature is different, but the ranges are wide enough that they overlap substantially. WebWhat is the density of O2 gas at STP? One mole of a gas at STP has a volume 22.4 L. So if we have the molar mass of the gas , just divide it by 22.4 to get the density of that gas. molar mass of O2 gas = 32 g/mol. Density = mass/volume = ( 32g/mol) / (22.4 L/mol) = 1.428 g/l 18 Ted Wrigley Philosophy, spirituality, science, mathematics, politics...
