Suppose a Voltaic/Galvanic cell at 298 K runs on the reaction, Sn(s) + Nr2+(aq) à Sn2+(aq) + Nr(s), where Nr is a fake element with the reduction potential, Nr2+(aq) + 2e- à Nr(s) E°1/2 = 0.40 V. The cell contains the following concentrations in each half cell: Sn(s) /Sn2+, [Sn(NO3)2] = 0.70 M Nr(s)/Nr2+, [Nr(NO3)2] = {M} M What is the value of Ecell? Answer format: Enter the answer in Volts but do not include the units. Enter 2 sig figs in standard, not scientific notation.
