density. Consider a 99.0 wt% NaCl-1.0 wt% MgCl2 solid solution. Given that the density of
pure NaCl is 2.16 g/cm³, compute the density of this solution assuming charge balance is
maintained by: (i) formation of Na+ vacancies, (ii) Mg2+ substituting with Na+ and additional
Cl- at interstitial sites, and (iii) Mg2+ occupying tetrahedral interstices with even more Cl-
interstitials forming. For the purposes of this problem, assume the lattice parameter remains
unchanged from that of pure NaCl.
