thumb_up100%
A cell is set up based upon these iron and copper redox couples: Cu/Cu2+ and Fe/Fe2+. Copper behaves as the cathode and when properly connected to a voltmeter, the standard cell potential is E° = +0.789 V. The concentration of copper ion is 1.00 M. The Fe2+ concentration is not known but the measured voltage is +(8.54x10^-1) V. At 298 K, what is the [Fe2+] concentration in the anode compartment?
The cell voltage is given in scientific notation (for example +(8.45x10^-1) V means 8.45x10-1 V). For this type of question, CourseLink requires that these numbers be in scientific notation. Your answer must also be expressed in scientific notation. Please watch the exponents carefully. We're not trying to be tricky. It is just necessary because the answers can cover a large range of values.
