Does temperature affect molality
WebMolality is a measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent. This contrasts with the definition of molarity which is based on a specified volume of solution.. A commonly used unit for molality in chemistry is mol/kg.A solution of concentration 1 mol/kg is also sometimes denoted as 1 molal.The unit mol/kg requires … WebJan 27, 2014 · 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 …
