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.

WebJul 31, 2024 · Molarity is a temperature-dependent parameter. The volume of a solution increases with an increase in temperature diye to increase in intermolecular spaces and vice versa. Hence, molarity is affected by temperature change. As Molarity (M) is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters. 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 27, 2014 · Explanation: Molarity changes with temperature. Molarity is moles of solute per litre of solution. Water expands as the temperature increases, so the volume of the solution also increases. You have the same number of moles in more litres, so the molarity is less at higher temperatures.
