eg...
KCl dissociates into K+ and Cl- ...so i = (1+1)/1=2
dep. in freezing point= iKm
osmotic pressure= iCRT
(P0 -P)/p0 = i X
note that i have done by no. of moles...
if u want to do using malar mass...than position of i will be on LHS
acetic acid in benzene forms a dimer...
If the substance does not fully associate or dissociate..than degree of dissociation comes into play...
