WebAug 31, 2024 · After appropriate stirring and subsequent decantation, a separation was observed between the opaque water/methanol phase and the limpid chloroform phase. Subsequent centrifugation at 5200× g for 5 min led to clarification of the water/methanol phase and creation of a dense, whitish interface between it and the bottom, chloroform … WebThe osmotic pressure of a solution increases as the number of particles of solute in the solution increases. The freezing point of pure chloroform is -63.5°C, and its freezing point depression constant is 4.07°C•kg/mol. If the freezing point of a solution of benzoic acid in chloroform is -70.55°C, what is the molality of this solution? 1.7 m
