Molarity other than solutions

[samanthaywu]

When is molarity used besides in solutions? Is it ever used for solids or gases?

[Jessica Katz]

molarity is a way to determine concentration of a solution so it cannot be used for solids and gas. It would normally be liquids in aqueous states because in molarity we are determining the concentration through volume rather than mass.

I believe that molarity involves a solvent (the universal solvent is water), capable of dissolving a certain amount of solute so the final product will be in the liquid form.

Molarity (moles of solute over liters of solution) is specifically referring to aqueous solutions, ie the ratio of solutes in a solvent, so no, it is never applied to solids or gases.

The units for molarity are mols/liters. This is only ever used to determine the concentration of a solution and is not used for solids or gases.

So one thing I would like to add is that when a solid is dissolved in water, it does in fact have molarity. However, outside of water, solids do not ever have a concentration. Gases usually do not have a concentration at all.

Molarity is a way to find the concentration of an aqueous solution, and can't be used to find out the concentrations in gases and solids.
