The electrode is given as:
For 1 mole of electrolysis, we require 2x96500C
The quantity of the charge passed can be given as
Number of moles of nickel in the electrolysis
Thus, number of moles of nickel deposited
Thus, 0.586 mol of Ni are present in 0.5 litre,
Thus, molarity of the left 2 M solution
