Calculating the molar mass of a solute from freezing point

Web8 okt. 2024 · The freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. WebThe freezing point depression is based on the molal concentration (moles of solute per kg of solvent). Δ T f = − k f ⋅ m You know the freezing point depression of the solution and the cryoscopic constant, so you can calculate the molality: m = − Δ T f k f = − − 1.23 ∘ C 1.86 kg ⋅ ∘ C mol = 0.66 m o l a l Web26 feb. 2024 · Δ T f = T f ( s o l v e n t) − T f ( s o l u t i o n) = K f × m. where Δ T f is the freezing point depression, T f (solution) is the freezing point of the solution, T f (solvent) is the freezing point of the solvent, K f is the … barandilla abatible
