Question

Is carbon dioxide litter than oxygen?

Answer 1

Air contains 78% nitrogen weighing 14 grams per mole, 21% oxygen weighing 32 g/mol and 0.9% argon weighing 39 g/mol. Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole. Hence, carbon dioxide has a higher density, or is heavier than air.
