WebAlso important is the role of the van’t Hoff factor “i”. For example, a 2.0 molal solution of NaCl has a particle concentration equal to 4.0 molal since each formula unit splits into two pieces (Na+ and Cl-) creating twice the number of free floating particles (ions). In this case the ideal van’t Hoff factor, iideal = 2.
