When the Ag+ concentration is 1.44 M, the observed cell potential at 298 K for an electrochemical cell with the following reaction is 3.269 V. What is the Mg2+ concentration? 2Ag+ (aq) + Mg(s) → 2Ag(s) + Mg²+ (aq) red Ag+ (aq) + e¯ → Ag(s) Eº = 0.799 V Mg²+ (aq) + 2e¯ → Mg(s) Fre = -2.370 V Mg²+] = M
