In concentrated aqueous solutions of NaCl, the Na+ (aq) ions can be so close to the
Cl- (aq) ions that a small percentage is associated in ion pairs at any given moment. Suppose that a solution contains 1.00 mol of NaCl and that 5.57% of the formula units exist in solution as such loosely bound pairs. How many ions are there in this solution?


Check my thinking on this:
1 mol NaCl contains 6.02E23 formula units of NaCl.
5.57% or 0.0557*6.02E23=?? will be present as NaCl loosley bound pairs.
The other 94.43% will ionize which will be 0.9443*6.02E23=xx formula units NaCl to ionize. Since those ionize to Na^+ and Cl^- you will have xx Na^+ and xx Cl^-. Add those together to obtain the total number of ions.
Remember to check my thinking.
