An aqueous solution of an unknown compound boils at 101.00 degrees Celsius (760 torr). What is the molality, and freezing point of this solution?

Answer 1

delta T = 101-100 = ??
delta T = Kb*molality
Solve for molality.

Now use the molality in the freezing point equation.
delta T = Kf*m
You have Kf and m, solve for delta T and convert to freezing point knowing the normal freezing point is zero C.

Answer 2

20

Answer 3

1000.0
