In acidic solution copper(I) ion is oxidized to copper(II) ion by nitrate ion. I got Cu^+(aq) + NO_3^-(aq) --> Cu^2+(aq) + NO_3^2-(aq)but itswrong
chem
for the E0cell i got 2.35 and for Q i got 8.186 then when i plugged that into the equation i get 2.7101V is that correct? I plugged 1 in for n.

You can easily do this by using a biology textbook or searching it on google.
chemistry
then do you subtract the given cell potential from that?
