A concentration cell is constructed of two hydrogen electrodes. The pressure of H2 is 1.00 atm in each hydrogen electrode. One of the electrodes is immersed in a solution with [H+] = 1.0 M and the other in a solution with 0.62 M NH3. What will be the value of Ecell? (Hint: First, you need to calculate [H+] for the NH3 solution.) Enter your answer with 3 significant digits. Enter scientific notation as 1.23E4.
