Molarity and molality are both measures of the concentration of a chemical solution. Molarity is the ratio of moles to volume of the solution (mol/L) while molality is the ratio of moles to the mass of the solvent (mol/kg)

Molality - Molality is a property of a solution and is defined as the number of moles of solute per kilogram of solvent. The SI unit for molality is mol/kg. A solution with a molality of 3 mol/kg is often
described as “3 molal” or “3 m.” However, following the SI system of units, mol/kg or a related SI unit is now preferred.
Molarity - In chemistry, molarity is a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.
