Question

If NaCl is doped with 10−4 mole % of SrCl2, the concentrate of cation vacancies will be : (NA=6.02×1023)mol−1

Answer 1

If you dump some sodium chloride into some water, the solution is conductive. That’s because the salt dissociates into sodium and chlorine ions after it hits the water. Ions are mobile and have a charge, and thus the solution can easily support electrical current.

Answer 2

Answer:

• 1 mole of SrCl2 → creates one mole cation vacancy.

Given

• 10^–3 mole of SrCl2 → creates 10^–3 × NA number of vacancy.

= 6.02 × 10^20 mol^–1
