Problem

A galvanic cell is assembled using an aluminum electrode in

Al^{3+}(aq)

and a nickel electrode in

Ni^{2+}(aq)

. After the cell delivers exactly 2.00 F of charge to an external circuit, what mass of the aluminum electrode has been consumed? (Molar mass of Al =

26.98\,\text{g}\,\text{mol}^{-1}

) a)

27.0\,\text{g}

39.1\,\text{g}

18.0\,\text{g}

9.0\,\text{g}
