The EMF of the cell: \( \mathrm{Zn}-\mathrm{Hg}\left(\mathrm{C}_{1} \mathrm{M}\right)\left|\mathrm{Zn}^{2+}(\mathrm{aq})\right| \) \( \mathrm{Zn}-\mathrm{Hg}\left(\mathrm{C}_{2} \mathrm{M}\right) \) at \( 25^{\circ} \mathrm{C} \), if the concentrations of the zinc amalgams are: \( C_{1}=10 \mathrm{~g} \) per \( 100 \mathrm{~g} \) of mercury, \( C_{2}=1 \) g per \( 100 \mathrm{~g} \) mercury, is
(a) \( 0.059 \mathrm{~V} \)
(b) \( 0.0295 \mathrm{~V} \)
(c) \( 0.59 \mathrm{~V} \)
(d) \( 0.295 \mathrm{~V} \)
