Question

Why does O2 diffuses faster than CO2 in the same room

Answer 1

Explanation:

When gases are diffusing through liquids, for example across the alveolar membrane and into capillary blood, the solubility of the gases is important. The more soluble a gas is, the faster it will diffuse. In this case carbon dioxide diffuses much faster than oxygen, as it is much more soluble.

Answer 2

Answer:

CO2 has a greater molar mass than O2

Explanation:

Carbon dioxide has one carbon atom and two oxygen atoms, and a molecular weight of 44 grams per mole ( a certain number of molecules). The oxygen in the air is actually O2, or molecular oxygen, with a molecular weight of 32. Hence, carbon dioxide has a higher density, or is heavier than oxygen.
