MgF2 --------> Mg+2 (aq) + 2F- (aq)

                        s                 2s

Ksp    = [Mg+2][F-]2

6.4*10-9   = s*(2s)2

6.4*10-9     = 4s3

s3                   = 1.6*10-9

s               = 1.17*10-3 M

solubility of mgF2 is 1.17*10-3 M

MgF2 --------> Mg+2 (aq) + 2F- (aq)

                        s                 2s

                        s                 0.05 +2s

Ksp    = [Mg+2][F-]2

6.4*10-9   = s*(2s+0.05)2

     s             = 2.6*10-6 M

solubility of MgF2 in NaF is 2.6*10-6 M
