Calculate the voltage, E, of the cell at \( 25^{\circ} \mathrm{C} \)
\[
\mathrm{Mn}(\mathrm{s}) \mid \mathrm{Mn}(\mathrm{OH})_{2} \text { (s) }\left|\mathrm{Mn}^{2+}(\mathrm{x} \mathrm{M}), \mathrm{OH}^{-}\left(2 \times 10^{-4} \mathrm{M}\right) \| \mathrm{Cu}^{2+}(0.675 \mathrm{M})\right| \mathrm{Cu}(\mathrm{s})
\]
\( \mathrm{P} \)
Given that \( \mathrm{K}_{\mathrm{sp}}=2.7 \times 10^{-13} \) for \( \mathrm{Mn}(\mathrm{OH})_{2}(\mathrm{~s}), \mathrm{E}^{0}\left(\mathrm{Mn}^{2+} / \mathrm{Mn}\right)=-1.18 \mathrm{~V} ; \mathrm{E}_{\mathrm{Cu}^{2+} / \mathrm{Cu}}^{0}=0.34 \mathrm{~V} \)
