What is the freezing point? Assuming equal concentrations, rank these aqueous solutions by their freezing point.? Find the molality of the solution prepared by dissolving 0. A pure sample of the solvent phenol has a freezing point of Calculate the freezing point of a solution of Kf for benzene is 5.

An unknown compound contains only carbon, hydrogen, and oxygen. Combustion analysis of the compound gives mass percents of The molar mass is determined by measuring the freezing-point depression of an.

The freezing point of a 0. It is a constant that is equal to the change in the freezing point for a 1-molal solution of a nonvolatile molecular solute. For water, the value of is So the freezing temperature of a 1-molal aqueous solution of any nonvolatile molecular solute is Every solvent has a unique molal freezing-point depression constant. These are shown in Table below , along with a related value for the boiling point called.

Ethylene glycol C 2 H 6 O 2 is a molecular compound that is used in many commercial anti-freezes. A water solution of ethylene glycol is used in vehicle radiators to lower its freezing point and thus prevent the water in the radiator from freezing.

Calculate the freezing point of a solution of Step 1: List the known quantities and plan the problem. This is a three-step problem. First, calculate the moles of ethylene glycol. Then, calculate the molality of the solution. Finally, calculate the freezing point depression. The normal freezing point of water is 0.

Therefore, since the freezing point decreases by Step 3: Think about your result.
