An ionic compound MCl is simultaneously doped with 10^(-6) mole % NCl_ – InterviewSolution

1.	An ionic compound MCl is simultaneously doped with 10^(-6) mole % NCl_2 and 10^(-7) mole % RCl_3.Calculate the concentration of cationic vacancies x. Express your answer as x/9xx10^14. (take N & R =divalent & trivalent cations)
Answer» SOLUTION :Conc.of cationic VACANCIES `=10^(-6)xx6xx10^(23)+10^(-9)xx6xx10^(23)xx2=6xx10^(15)+12xx10^(14)=(60+12)xx10^14=72xx10^(14)`
