Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations.
A galvanic cell at a temperature of 25.0 °C is powered by the following redox reaction:
2+
2+
Sn²+ Ba(s)
(aq) + Ba (s) Sn (s) + Ba²+ (aq)
→>>
Suppose the cell is prepared with 6.10 M Sn
