Solve this VIISometimes the type of defects present in a material can be determined by measuring itsFile Previewdensity. Consider a 99.0 wt% NaCl-1.0 wt% MgCl2 solid solution. Given that the density ofpure NaCl is 2.16 g/cm³, compute the density of this solution assuming charge balance ismaintained by: (i) formation of Na+ vacancies, (ii) Mg2+ substituting with Na+ and additionalCl- 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 remainsunchanged from that of pure NaCl.

Calculate the density of the NaCl-MgCl₂ solid solution based on the three possible scenarios.Step 1:…
