If NaCl is doped with 10^(-3) mol % of SrCl_(2) what is the concentration of cation vacancy?

Answer»

Solution :ONE cation of `SR^(2+)` would create one cation vacancy in NaCl.
`:.`Concentration of cation vacancy on being doped with `10^(-3)` mol% `SrCl_(2)`
`= 10 ^(-3) mol%`
`=(10 ^(-3))/(100) "mol"`
`=(10 ^(-3))/(100) XX 6.02 xx 10^(23)`
cation vacancies PER mole
`= 6.02 xx10^(18)`cation vacancies per mole.
