In a large number of samples of water, in which the copper ion concentration is expected to be quite small, [Cu2+] was measured using an electrochemical cell. This consisted of a silver electrode dipping into a 1.00 M solution of AgNO3, which was connected by a salt bridge to a second half-cell containing a copper electrode. The copper half-cell was then filled with the water sample. In one analysis, the cell potential at 25 oC was measured to be 0.62 V. What was the concentration of Cu2+ in this sample of water? ? (?u2+/?u)= +0.34 V; ? (?g+/g )= +0.80 V

I'm unsure of how to put it into the calculator? I read that it was ln instead of log. Do i type it all in together and then hit enter?
