1g of a monobasic acid dissolved in 200g...

`1g` of a monobasic acid dissolved in `200g` of water lowers the freezing point by `0.186^(@)C`. On the other hand when `1g` of the same acid is dissolved in water so as to make the solution `200mL`, this solution requires `125mL` of `0.1 N NaOH` for complete neutralization. Calculate `%` dissociation of acid ? `(K_(f)=1.86(K-kg)/("mol"))`
