Given the measured cell potential, E cell is -0.3603 V at 25°C in the following cell, calculate the H+ concentration
Pt(s)|H2(g,0.713 atm)|H+(aq, ? M)||Cd2+(aq 1.00 M)|Cd(s)

The balanced reduction half-reactions for the cell, and their respective standard reduction potential values, E o, are as follows.
2H+(aq) + 2e- —> H2(g).[Eo=0.00 V]
Cd2+(aq)+2e- —> Cd(s). [Eo=-0.403V]
