Explanation / Answer

There are multiple questions here . i am allowed to answer only 1 at a time. I will answer 1st one for you. Please ask other as different question.

Mass of CuCl = 9.9*10^-3 g
Molar Mass of CuCl = 99 g
number of moles of CuCl = mass / molar mass
                                                    = (9.9*10^-3) / (99)
                                                    =1*10^-4 mol

[CuCl] = number of moles / volume
              = 1*10^-4 / 1
               = 1*10^-4 M

[Cu+] = 1*10^-4 M
[Cl-] = 1*10^-4 M

[K+]= 0.1 M
[CN-]= 0.1 M
