Which is denser, a solid solution, a gaseous solution, or a liquid solution

Gaseous solution isn't dense, neither the solid, but liquid is denser

Explanation:

Gas: only gases are dissolved under a given set of conditions. Since interactions between molecules play almost no role, dilute gases form rather trivial solutions. In part of the literature, they are not even classified as solutions, but addressed as mixtures.

Liquid: If the solvent is a liquid, then almost all gases, liquids, and solids can be dissolved.

Solid: Solid solution is less denser than liquid.
