WebDefinition: Molarity of a given solution is defined as the total number of moles of solute per litre of solution. The molality of a solution is dependent on the changes in physical properties of the system such as pressure and temperature as unlike mass, the volume of the system changes with the change in physical conditions of the system. WebJan 22, 2024 · Molarity – number of solute particles in a solution. The difference between osmolarity and molarity is explained by the van’t Hoff factor – the number of moles (not the mass or weight) of dissociated solute particles (ions) in a solute. For example, a 1 mol/L glucose solution does not dissociate; the van’t Hoff factor is, therefore, one. iron blooded orphans weaponsWebAnswer: 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. iron bmp6
