Quizplus · Accepted Answer

The standard cell potential can be calculated using the formula:
E°cell = E°cathode - E°anode
where E°cathode is the standard reduction potential of the cathode (Ag), and E°anode is the standard reduction potential of the anode (Co).
Substituting the given values, we get:
E°cell = E°cathode - E°anode
E°cell = 0.8 V - (-0.277 V)
E°cell = 1.077 V
Therefore, the correct choice is A.
