The purpose of this experiment was to observe and measure the effect of an unknown solute on the freezing point of a solvent and to determine the molar mass (molecular weight) of said unknown solute. In the experiment, the solvent, cyclohexane, and the unknown solute “Spongebob” were used throughout the experiment. According to theory as the unknown (nonvolatile) solute was added in the solution the vapor pressure should have decreased. When the vapor pressure decreases the freezing point will decrease along with it in the solution. In the experiment the cooling curves corresponds with that hypothesis. The freezing point of cyclohexane appeared to decrease more each time the unknown solute, “Spongebob,” was added to the solution. From the data
