Calculate the concentration of a KMnO4 solution if the titration of a 10 mL sample required 45.0 mL of a H2C2O4 solution with a concentration of 0.350 M to reach the endpoint. 6 H+ + 2 MnO4⁻ + 5 H2C2O4  →                                                         2 Mn2+ + 8 H2O + 10 CO2

Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C. (The equation is balanced.) Mg(s) + 2 Ag⁺(aq) → Mg2+(aq) + 2 Ag(s) Mg2+(aq) + 2 e⁻ → Mg(s)      E° = -2.28 V Ag⁺(aq) +  e⁻  → Ag(s)          E° = +0.80 V
