Answer:
Given that t
freezing point depression constant, Kf = 0.777 C/m
Normal freezing point = 39.8 degree centigrade
Concentration in molality = 1.42 × 100 = 1.42 m
So, (delta T) = Kf × m = 0.777 × 1.42 = 1.103
So, the freezing point is lowered by 1.103 degree centigrade.
So the predicted freezing point is = 39.8 - 1.103
= 38.69 degree centigrade.
