Answer:

2.459 V

Explanation:

If we look at the data we have from the question closely, we will discover that aluminum has a very negative reduction potential. Recall that very negative reduction potentials are associated with strong reducing agents.

Similarly, silver has a positive reduction potential signifying that it is an oxidizing agent. Since the reducing agent is oxidized in a redox reaction and the oxidizing agent is reduced.

Hence;

E°cell= E°reduction process - E°oxidation process

E°cell= 0.799 -(-1.66)

E°cell= 2.459 V
