WebFeb 26, 2024 · Molality. Molality is defined as the number of moles of solute per kilogram solvent. Be careful not to use the mass of the entire solution. … WebFeb 17, 2024 · Molality is used because mass doesn't depend on temperature (in a closed system at least). Compared to molarity (mass per volume) it is thus more accurate because it's temperature invariant. But how can a solvent (e.g water) have mass in the first place? Since solvents are fluids which have only volume? WebConcentrations 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. dwr-956m home gateway
