you have to use this equaion :ΔTF = KF · b · i

What do I do next?

First you have to know KF, the cryoscopic constant of Poly Vinyl alcohol. then you have to calculate b. it is molality of the solution. then i which is number of ion particles per individual molecule of solute and apply these values in the equation.
