Transcribed Image Text:If potassium nitrate (KNO3; FW 101.1 amu) was combined with a
known volume of cyclohexane (C6H12; FW = 84.14 amu)
A. the freezing point of this mixture would be lower than the freezing point of
cyclohexane by the product of the Kr for cyclohexane (20.5 °C/m) times the
calculated molality of the mixture.
B. the freezing point of this mixture would be lower than the freezing point of
cyclohexane by two times the product of the Kr for cyclohexane (20.5 °C/m)
times the calculated molality of the mixture. (the i factor would be 2)
C. the freezing point of this mixture would be higher than the freezing point of
cyclohexane by the product of the Kr for cyclohexane (20.5 °C/m) times the
calculated molality of the mixture.
D. the freezing point of this mixture would be higher than the freezing point of
cyclohexane by the product of the Kr for cyclohexane (20.5 °C/m) times the
calculated molality of the mixture.
