A galvanic cell at a temperature of 25 C is powered by the following redox reaction:
2MnO-4(aq)+16H^+(aq)+5Pb(s)=2Mn^2+(aq)+8H2O(l)+5Pb^2+(aq)

Suppose the cell is prepared with 4.94 M MnO-4 and 0.524 H^+ in one half-cell and 6.46 M Mn^2+ and 0.313 M Pb^2+ in the other.

Calculate the cell voltage under these conditions. Round your answer to 3 significant digits.
