The same amount of electricity was passed through two separate electrolytic cells containing solutions of nickel nitrate $[\mathrm{Ni(NO_3)_2}]$ and chromium nitrate $[\mathrm{Cr(NO_3)_3}]$ respectively. If $0.3\,\text{g}$ of nickel was deposited in the first cell, the amount of chromium deposited is: (at. wt. of Ni $= 59$, at. wt. of Cr $= 52$)
