So im having trouble with these 2 EMF question, and I dont know where to start.

Express the EMF of the cell

Pt/In(s)/In_{2}(SO_{4})_{3}(aq,m)/Hg_{2}SO_{4}/Hg(l)/Pt'

in terms of E^{0},t ,y(gamma), m of In_{2}SO_{4}(aq)

and...

Calculate the E_{298} for the cell

Cu_{l}/Zn/ZnCl_{2}(0.0100m/Kg)/AgCl(s)/Ag/Pt/Cu_{r}

given gamma of ZnCl_{2} is .708V at this molarity and temperature
