Suppose a Voltaic cell at standard conditions, runs on the reaction,  Sn(s) + Nr2+(aq)   à  Sn2+(aq) +   Nr(s) The standard cell potential, E°cell = 0.30 V. What is the new value of Ecell if the concentrations are changed to  [Sn2+] =  {M} M       and         [Nr2+] =  .30 M? Hint:  The voltage will be less than E°cell       Answer format:  Enter the answer in Volts but do not include the units.  Enter 2 sig figs in standard notation.
