How do you find I when using Van't Hoff factor. For example I need it to solve the following problem but am struggling to find where the I comes from Calculate the freezing point and boiling point in each solution, assuming complete dissociation of the solute. Calculate the freezing point of a solution containing 14.2 g FeCl3 in 155 g water.
