What is the freezing point of a solution of 5grams of CaCO3 and 10ml of H20?

    The freezing point depression equation is
    delta T = Kf*molality where Kf is 1.86 degrees/m for water. However, CaCO3 is not very soluble in water, certainly not to the extent of 5 g/10 mL water so one would need to go through the Ksp equation to determine the solubility, then apply delta T = i*Kf*m where i = 2.
