For the electrochemical cell below, the half-cell on the left is the anode and the cell potential is 0.165 V at 25 °C. What is the concentration of H+, x, in mol L-1?  Note: The symbol M is an abbreviation for mol L-1.

Pt(s) | V2+(aq, 0.670 M) , V3+(aq, 0.350 M) || H+(aq, x M ) | H2(g, 1.20 bar) | Pt(s)

Half reaction  E ° / V 2 H+(aq) + 2 e-  ?

H2(g) 0.000 V3+(aq) + e-  ?

V2+(aq)-0.255

Enter a value accurate to 3 significant figures.

x = [H+] =    mol L-1
