Question

20. A mixture of three gases, A (density = 0.91), B (density = 0.52) and C (density = 0.72) is enclosed in a vessel at constant temperature when equilibrium is established. The observation which is most likely to occur is Gas A will be at the top in the vessel Gas B will be at the top in the vessel Gas c will be at the top in the vessel The gases will mix homogenously throughout the vessel
