Question

earning Goal o learn how to use the Nernst equation The standard reduction potentials listed in any eference table are only valid at the common eference temperature of 25 C and standard conditions of 1 M for solutions and 1 atm for gases To calculate the cell potential at honstandard conditions one uses the Nernst equation 2 303 RT n F E E log10 Q where E is the potential in volts E is the standard potential at 25 C in volts R 8 314 J K mol is the gas constant T is the temperature in kelvins n is the number of moles of electrons transferred F 96 500 C mol e is the Faraday constant and Q is the reaction quotient At the common reference temperture of 298 K substituting each constant into the equation the result is at 55 C where Fe2 2 90 M and Mg2 0 310 M Part A Part B Part C Mg s Fe aq Mg aq Fe s What is the value for n Express your answer as an integer and include the appropriate units i e enter mol for moles View Available Hint s A
