Explanation / Answer

1. option 2nd

2. option 2nd and fourth

3.option B

-----------------------------------------------------------------------

the solution is 0.0340 F

[Mg^2+] = formality * activity coeeficient

             = 0.0340 F * 0.23

             = 7.82 *10^3

Ionic strength = C* i

                     = 1/2 (7.82 *10^3 * 1)

                      = 3.91 *10^3
