WebMay 4, 2024 · Concentrations expressed in molality are used when studying properties of solutions related to vapor pressure and temperature changes. Molality is used because its value does not change with changes in temperature. The volume of a solution, on the other hand, is slightly dependent upon temperature. What are the 4 colligative properties? WebMolarity is the function of the mole of solute and volume of the solution so, molarity will be affected by the change in temperature. Why does moles increase with volume? Avogadro Law gives the relationship between volume and …
