WebMolarity is the number of moles in solute per unit volume of solution. As the temperature rises, the volume of the solution expands and the volume of the solution increases. When … WebIn general, the molar conductivity of an electrolytic solution is the conductance of the volume of the solution containing a unit mole of electrolyte that is placed between two electrodes of unit area cross …
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.
