A galvanic cell consists of a Zn|Zn^{2+} electrode (where [Zn^{2+}] = 0.010 M) and a Cu|Cu^{2+} electrode. The standard cell potential is (E^{\circ}=1.10\ \text{V}\). At 25 °C the observed cell potential is (E=1.05\ \text{V}\). Assuming the reaction is Zn(s) + Cu^{2+}(aq) \rightarrow Zn^{2+}(aq) + Cu(s), calculate the concentration of Cu^{2+} in the cell.
