"WebMay 29, 2014 · The van't Hoff factor is essentially the number of particles a unit or molecule breaks into when it is dissolved. For example, sodium chloride (NaCl) breaks into 2 ions, so its van't Hoff factor is 2. Calcium chloride (CaCl2) would have a factor of 3. Molecular substances such as sucrose or glucose do not ionize, so their factor is 1. " - Cyclohexane van't hoff factor
