WitrynaUncategorized. At all temperatures and pressures, oxygen is denser than both air and nitrogen, but only slightly. We usually don’t worry about which is lighter or heavier because they don’t separate from each other. The difference in density between nitrogen and oxygen gas is due to their small molecular weight (4 g/mol). Witryna21 wrz 2024 · Methane.
