Answer 2

Answer: Molarity and molality are both measures of the concentration of a chemical solution. Molarity is the ratio of moles to the volume of the solution (mol/L) while molality is the ratio of moles to the mass of the solvent (mol/kg). Most of the time, it doesn't matter which unit of concentration you use.
