A solution in which no more solid can be dissoved is referred to as [saturated?] In such a solution, the concentration of solute is called the ____ when reported in g/L and the [molarity?] when reported in mol/L.

Does anybody know what might go in that blank by any chance?

The unit for density of gases is g/L but I've never heard of that term being used for any solute in solution.

Yeah me neither! Thanks though DrBob

solubility!

Yes, the blank can be filled with the word "solubility".

When a solution is saturated, it means that the maximum amount of solute has been dissolved in the solvent, and no more solute can be dissolved at that temperature and pressure.

The concentration of solute in a saturated solution can be reported in different ways.

When it is reported in grams per liter (g/L), it is called "solubility" -- indicating the maximum amount of solute that can dissolve in a given volume of solvent at a specific temperature.

When it is reported in moles per liter (mol/L), it is called "molarity" -- representing the number of moles of solute dissolved in one liter of solvent. Molarity is calculated by dividing the number of moles of solute by the volume in liters.

So, in summary, the concentration of solute in a saturated solution is referred to as solubility when reported in g/L and molarity when reported in mol/L.
