What do chemists think is the best measurement of concentration for describing the concentration of a solid solute dissolved in one liter of a liquid solution?

Molarity.

Explanation:

M = (mass / molar mass) of the solute (1000 / volume of the solution).

So, the best measurement of concentration for describing the concentration of a solid solute dissolved in one liter of a liquid solution is Molarity.
