Assuming that the concentration of Cu2+ ions in a solution is 0.25 M, the concentration of Ag+ ions in another solution is 0.50 M, and the standard reduction potential of Cu2+(aq) + 2e- → Cu(s) is +0.34 V and that of Ag+(aq) + e- → Ag(s) is +0.80 V, calculate the current density when the two solutions are separated by a salt bridge and connected by a wire.
