The mole fraction of potassium nitrite (KNO2) in a solution is 0.0194. The solution density is 1.0627 g/ml. Calculate the molarity of the solution
Why is it necessary to express the concentration of solute in units of molality rather than molarity? O The molality is based on the volume of the entire solution, whereas molarity is based only on the volume of the solvent. Molality will be constant at any temperature, whereas the concentration can change as the solution expands with heat. The molality is based on the mass of the entire solution, whereas molarity is based only on the mass of the solvent.
