WebQuestion. The van't Hoff factor for FeCl 3 equals 3.4. The freezing point depression constant, K f, equals 1.86 0 C/m for water. Calculate the freezing point of water if 0.75 moles of FeCl 3 are dissolved in 500.0 g of water. Group of answer choices. WebDec 31, 2013 · Step 2: Determine the van't Hoff factor. The van't Hoff factor, #i#, is the number of moles of particles obtained when 1 mol of a solute dissolves. Nonelectrolytes such as sugar do not dissociate in water. One mole of solid sugar gives one mole of dissolved sugar molecules. For nonelectrolytes, #i = 1#.
