(C) An organic acid is distributed between 500mL each of solvent A and water. In water it is dissociated. The amount of the acid in aqueous layer was 6 grams and in solvent A it was 0.72grams. If the distribution coefficient of the acid between the solvent A and water is 0.16. Calculate the degree of dissociation, assuming that the acid has normal molecular mass in A. (06Marks)
