Calculate the emf of the following cell ...

Calculate the emf of the following cell at 298 K :
`Al(s) |Al^(3+)(0.001 M) || Ni^(2+) (0.1M)|Ni(s)`
[Given:`E_(Al^(3+)//Al)^o=-1.66V ,E_(Ni^(2+)//Ni)^o=-0.25V, log 10=1]`
(ii) With the help of a graph explain why it is not possible to determine `wedge_m^o` for a weak electrolyte by extrapolating the molar coductivity `(wedge_m^o)` versus `C^(1//2)` curve as for strong electrolyte.
