the values of observed and calculated molecular weights of silver nitrate are 90 and 170 respectively. the degree of dissociation of silver nitrate is
Van't Hoff factor (i) = calculated Mol. mass / Observed Mol. mass
i = 170 / 90
i = 1.88
degree of dissociation α = (i - 1) / (n - 1) ( n = no. of ions formed after dissociation ) α = (1.88 - 1) / (2 - 1) ( The dissolution of silver nitrate from ions of silver and nitrate) α = 0.88
