An Ecell consists of a Ag electrode in contact with 346 mL of 0.1 M silver nitrate solution and a Mg electrode in contact with 288 ml of a 0.1 M Mg(NO3)2 solution now you just need to calculate the value for E for the cell at 25 the temperature of twenty five degree Celsius and also compute A current is drawn from the cell until 1.20 grams of Ag have been deposited at the Ag electrode. Determine the value of E for the cell at that stage of operation.
