The freezing point of distilled water was determined by recording a thermogram: -0.176 degrees Celsius. The freezing point of a 0.200 m (molality) solution containing an unknown, ionic compound was determined by recording a second thermogram: -.904 degrees Celsius.
a. Determine the freezing point depression, (delta)Tf, for the ionic solution.
b. Determine effective molality (m_effective) for the ionic solution.
c. Determine the van't Hoff factor, i, for the ionic compound.
