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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
