Question

If the freezing point depression for a solution is 2.5°c and kf = 4.5°c/m, what is the molality of the solution?

Answer 1

If the freezing point depression for a solution is 2.5°c and kf = 4.5°c/m, the molality of the solution is

m= 0.56m

What is molality?

While molecular weight (MW) and molecular weight (MW) may be used to measure concentration, molecular weight (MW) and molecular weight (MW) is used to measure molecular weight and concentration, respectively.

What is the molality of the solution?

Generally, the equation for  of freezing point of depression with molality is  mathematically given as

$\Delta T_{f} = k_{f} *m$

Therefore

m = 2.5/4.5

m= 0.56m

In conclusion,  the molality of the solution  is 0.56m
