    E° = 1.24 V

    Explanation:

    Let's consider the following galvanic cell: Fe (s) | Fe²⁺ (aq) || Ag⁺ (aq) | Ag (s)

    According to this notation, Fe is in the anode (where oxidation occurs) and Ag is in the cathode (where reduction occurs). The corresponding half-reactions are:

    Anode: Fe (s) ⇒ Fe²⁺ (aq) + 2 e⁻

    Cathode: Ag⁺ (aq) + 1 e⁻ ⇒ Ag (s)

    The standard cell potential (E°) is the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode.

    E° = E°red, cat - E°red, an

    E° = 0.80 V - (-0.44 V) = 1.24 V
