Expert Answer:

Introduction of one Sr2+ introduces a cationic vacancy because one Sr2+ replaces two Na+ ions.

Therefore, introduction of 10-3 moles of SrCl2 per 100 moles of NaCl would introduce 10-3 mole cation vacancies in 100 moles of NaCl.                (1)

Number of vacancies per mole of NaCl
