E^ocell for the reaction Fe⁺² + Zn⁺² = Fe⁺³ + Zn (not balanced) is -1.53 v. What is K for this reaction?

I'm having a hard time on this one as the answer isn't really given.

So here's my shot...

Using this equation

E^ocell = .0592/n log K

-1.53= .0592/2 log K
-1.53=.0296 log K
-1.53/.0296 = log K
-51.689 = log K
K = antilog (-51.689)
K= 2.06 x 10^-52

Is there another example where the answer for this question would be 2 or more Faraday's?

23.0 grams of sodium are electroplated during the electrolysis of molten sodium chloride.
How many Faraday's of charge were needed for this electrolysis if the reduction reaction for sodium is Na⁺¹ + 1e^-1 = Na?

This one would be 1 Faraday, or is it all just based on the electron lost? There were other questions in the book, but all were 1 Faraday's.

Thanks
