A 0.150 aq MgSO4 solution has a measured freezing-point depression of 0.325°C. FIND the Van't Hoff factor for MgSO4 at this concentration?
Ahhh! I know it's like reading Egyptian wall paintings :/ thanks!

Change in freezing point = i kf m
(I'm assuming that the concentration of the solution is 0.150 m, and that this is an aqueous solution.)
For water, kf = 1.86 C/m. So
0.325 = i (1.86 C/m) (0.150 m)
i = 1.16
