For the electrochemical cell, Mg(s)|Mg2+(aq.1 M)||Cu2+(aq.1 M)|Cu(s) the standard emf of the cell is 2.70 V at 300 K. When the concentration of Mg2+ is changed to x M, The cell potential change to 2.67 V at 300 K. The value of x is _________(given, F/R=11500KV−1, Where F is the Faraday constant and R is the gas constant, ln(10)=2.30)
