Thank you for the opportunity to help you with your question!

center of mass =

= ( 0*34.6 + 12.00*23) / (34.6 + 23)

= 4.79nm away from the center of chlorine ion

(OR 12 - 4.79 = 7.21nm away from the center of sodium ion)
 

** P/S: Please remember to give me a review later on once the answer is correct. I would be highly appreciate it. Thank you. **
