When a molecule forms a hydrogen-bonded dimer as shown in your lab manual on pg 162 or is an electrolyte, you need to account for Van't Hoff factors. For the dimer shown in manual, you would expect the Van't Hoff factor to be Blank 1__________ (1 dec place). For NaCl, you would expect the Van't Hoff factor to be Blank 2__________ (0 dec place).
