Expert Answer:

Standard electron potential of Copper is 0.34 V.
The electrode reaction written as 
Cu to the power of plus 2 space end exponent space plus space 2 straight e to the power of minus space rightwards arrow Cu

straight E equals straight E degree minus fraction numerator 0.0591 over denominator 2 end fraction log 1 over Cu
straight E equals 0.34 minus fraction numerator 0.0591 over denominator 2 end fraction log fraction numerator 1 over denominator 0.1 end fraction
straight E equals 0.3104 space straight V
