Answer:

The total number of cation vacancies formed on doping of MgCl₂ crystal with AlCl₃ is 3.0115×10¹⁷.

Explanation:

Number of moles of AlCl₃ in 1 mole of MgCl₂ =\frac{10^{-4}}{100} =10^{-6}moles

When MgCl₂ crystal is doped with AlCl₃, to keep the crystal electrically neutral, three Mg^{2+} replaced by two Al^{3+} and one cation vacancy is created.

Therefore 2 moles of AlCl₃  will form = 1mol of cation vacancies

10^{-6}moles AlCl₃ will form cation vacancies =\frac{10^{-6}}{2}=0.5*10^{-6}mol

Total number of cation vacancies in  MgCl₂ crystal will be: =0.5*10^{-6}*6.023*10^{23}

=3.0115*10^{17} cation vacancies
