### 6M.5

Determine the standard cell potential:
2NO3(-)(aq) + 8H(+)(aq) + 6Hg(l) -->3Hg2(+2)(aq) + 2NO(g) + 4 H2O(l)

Thanks!

follow up for this question.. what would be the number of moles to obtain delta G?

The number of moles involved for calculating the delta G (n) is the moles of electrons transferred overall. Be sure the electrons used in the reduction half reaction and the oxidation half reaction are the same. If not you will have to scale them so they can be the same.

Thanks!

To find the standard cell potential, write the half reactions first then subtract the anode cell potential from the cathode cell potential and you should get +0.17 V
