1) Some of the cyclohexane solvent vaporized during the temperature versus time measurement. Will this loss of cyclohexane result in its freezing point being recorded as too high, too low, or unaffected? Explain.2) The solute dissociates slightly in the solvent. How will the slight dissociation affect the reported molar mass of the solute - to high, too low, or unaffected? Explain. 3) Interpretation of the data plots consistently shows that the freezing points of three solutions are too high. As a result of this "misreading of the data," will the reported molar mass of the solute be too high, too low, or unaffected? Explain
