The depression in freezing point for 2 molal solution of A in the same solvent is 6 K. The ratio of K b and K f i.e., K b /K f is 1 : X. The value of X is [nearest integer] WebAnswer: The molal elevation constant is the elevation in the boiling point of a solvent when one mole of a non-volatile solute is dissolved in it per kilogram of solvent. The unit of molal elevation constant is given as Kkgmol−1. Here, m is molality or the number of moles of the solute dissolved in a kg of solvent. god\u0027s covenant with noah kj thesis
