WebMolality is used because its value does not change with changes in temperature. The volume of a solution, on the other hand, is slightly dependent upon temperature. ... Thus, molality involves only masses which do not change with temperature whereas molarity involves volume which change with temperature. Hence, molality is preferred over ... 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.

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. imb bank head office wollongongWebApr 6, 2024 · Case 1: When temperature increases, volume also increases and consequently molarity of a solution decreases because molarity follows an inverse relation with both … imb bank share price asx
