We desire a concentration of Na+ ions at a concentration of 1018Na+/cm³. Determine the mass of NaCl required to be added to 4L of pure H₂O to achieve the desired concentration assuming complete dissociation. The atomic weights of the elements can be found on any standard periodic table. Assume Avogadro's number to be 6.02×1023atoms/mole and 1L = 1,000 cm³. (comment on how you might facilitate the mixture you calculate, e.g. final weight measurable ?
