complete the following table and calculate the decrease in the freezing point of water when 1 mol glycerol (CH3OH-CHOH-CH2OH), NaCI or Na2CO3 is dissolved in 1.00 kg of water

The decrease in the freezing point of the solution is −1.86oC.

What is the decrease in the freezing point?

Now we know that the freezing point depression of a solid is a colligative property of the solution.

Thus we have that;

ΔT = K m i

ΔT = freezing point depression

K = freezing constant

m = molality of the solution

i = Van't Hoff factor

Thus;

molality =  1 mol/1 Kg = 1 m

ΔT = −1.86oC/m * 1 m * 1

ΔT =−1.86oC
