According to Faraday's first law of electrolysis, the mass of substance deposited ($w$) is proportional to

If \(E^\circ_{MnO_4^-/MnO_2} = x \, V\) and \(E^\circ_{MnO_2/Mn^{2+}} = y \, V\), what is the value of \(E^\circ_{MnO_4^-/Mn^{2+}}\)?

The standard Gibbs energy \(\Delta G^0\) for the electrochemical cell: \[ \text{P(s)} | \text{P}^{3+}(\text{aq}, 0.01\,\text{M}) || \text{Q}^{2+}(\text{aq}, 0.02\,\text{M}) | \text{Q(s)} \] with \(E^0_\text{cell} = 0.2 \, \text{V}\) is:
