Methodology of the experiment: Determination of the molecular weight of a solute by depression of
freezing point method.
The following method can be used to determine the molar mass of solute by using the freezing point
depression.
Apparatus:
i) A freezing tube with a side-arm to contain the solvent or solution, while the solute can be
introduced through the side-arm.
ii) An outer largertube into which is fixed the freezing tube, the space in between providing an
air jacket which ensures a slower and more uniform rate of cooling.
iii) A large jar containing a freezing mixture.

Procedure:
15 to 20 g of the solvent is taken in the freezing point tube and so that the bulb of thermometer...
