The boiling point of water in a 0.1 molal silver nitrate solution (solution A) is x∘C. To this solution A, an equal volume of 0.1 molal aqueous barium chloride solution is added to make a new solution B. The difference in the boiling points of water in the two solutions A and B is y×10−2 ∘C(Assume : Densities of the solutions A and B are the same as that of water and the soluble salts dissociate completely.Use : Molal elevation constant (Ebullioscopic Constant), Kb =0.5K kg mol−1;Boiling point of pure water as 100∘C.) The value of |y| is ___. |
