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. WebThe mole fraction of nitrogen is 0.8. Hence,the partial pressure of nitrogen=P T×X=0.8×5=4 atm.
