When 9.12 g of HCl was dissolved in 190 g of water, the freezing point of the solution was -4.65oC. What is the value of the van't Hoff factor for HCl?
Here is what I did-
I know that I use: deltaT= Kf x m x i
rearranged to solve for i: deltaT/Kf x m
solving for molality:
kg solvent= .190
i= -4.65oC/1.86 x 1.32 = -1.89
I am not sure if the value for i can be negative or if I did the problem correctly. Please help me! Thanks!
