Densities of Aqueous Solutions of Inorganic Sodium Salts
Be aware of the concentration units in the figures:
wt%: Mass of solute/total mass of solution*100%
mol/kg: Molality = moles of solute/kg of water
mol/liter: Molarity = moles of solute/liter of solution
Values are tabulated below the figures.
