Hi!
Could someone help me with part b i) and ii) of this question about galvanic cell? part bi and ii are pasted in below, but the question stem is attached.
part b
After a period of time, a solid deposit that had formed on the copper electrode was removed and dried. The deposit had a mass of 0.395 g.
i) Calculate the final mass of the nickel electrode.
ii) Calculate the final concentration of the nickel (II) nitrate solution.

Thank you!
