WebAboutTranscript. The most common way to express solution concentration is molarity (M), which is defined as the amount of solute in moles divided by the volume of solution in liters: M = moles of solute/liters of solution. A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution. Created by Sal Khan. WebMolarity is the ratio of a solvent’s moles to a solution’s total litres. Both the solute and the solvent are part of the solution. Molality, on the other hand, is the ratio of the solute moles to the solvent kilogrammes. Mole fraction is the mole of a constituent divided by the total mole of all constituents in a mixture.
