which solution has highest freezing point if all are at the same molality

calcium chloride
sodium nitrate
potassium sulfate
iron(III) nitrate
all have same freezing point

please explain

  • chemistry -

    look at the formulas:
    CaCl2 ...three particles
    NaNO3....two particles
    K2SO4...three
    Fe(NO3)3...four
    Fe(NO3)3 will have the lowest freezing point (greatest freezing point depression), and sodum nitrate has the least depression, so it will have the highest fp.
