A galvanic cell is assembled from a Zn²⁺/Zn half-cell and a Cu²⁺/Cu half-cell. The standard cell potential is E° = 1.10 V, and each half-reaction involves 2 electrons. At 298 K, the ion concentrations are [Zn²⁺] = 0.010 M and [Cu²⁺] = 1.0 M. Calculate the cell potential E under these nonstandard conditions (in volts).
