Mole fraction of solute in some solution...

Mole fraction of solute in some solution is `1//n` . If `50%` of solute molecules dissociate into two parts and remaining `50%` get dimerised , new mole fraction of solvent becomes `4//5` . Find value of n.29. 0.1 M KI and 0.2 M are mixed in 3:1 volume ratio . The depression in freezing point of the resulting solution will be 0.1 x (Assume `K_(f)` of and molality =molarity). Then x=_________
