Calculate the standard biological potential of NAD+/NADH couple at 25oC from the standard reduction potential:
NAD+(aq) + H+(aq) + 2e- --> NADH(aq), Eo = -0.11V
There is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of Magnesium metal consumed in the reaction, therefore moles of H2 evolved = moles Mg consumed and the atomic weight of Mg = weight of Mg consumed..
