Solve this and show all of the calculations 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.

You are given a sample of polypropylene and wish to find out the volume % crystallinity. You know that the density of 100% crystalline polypropylene (ρc) is 0.946 g/cm3, and the density of 100% amorphous polypropylene (ρa) is 0.855 g/cm3. Through your careful measurements, you determine the density of the sample (ρs) is 0.93 g/cm3. Use the following equation to determine the volume % crystallinity (ν) of your sample. Enter your answer with 1 decimal place. Answer is 82.4 Another sample of polypropylene has a 68 volume percent crystallinity. What is the density of the sample? Enter your answer is g/cm3. ( I need help with this second question. The answer is .917, i just can't get to that.) Hint: use the values and equation from the previous problem.
