The right compartment of a zinc concentration cell is prepared by dissolving $18.9\mathrm{g}$ of $\mathrm{Zn}(\mathrm{NO}{}_3){}_2$ (molar mass $189\mathrm{g}\mathrm{mo}{\mathrm{l}}^{-1}$) in water to make $500\mathrm{mL}$ of solution. The left compartment contains $0.005\mathrm{M}$ $\mathrm{Zn}(\mathrm{NO}{}_3){}_2$. Both have zinc electrodes; T = 298 K, $2.303RT/F=0.0591\mathrm{V}$, $\log 2=0.301$. Which statements are correct?

1. A$[\mathrm{Zn}{}^{2+}]$ in the right compartment is $0.20\mathrm{M}$
2. BThe cell EMF is about $47\mathrm{mV}$
3. CThe left electrode is the anode
4. DThe EMF doubles if both solutions are diluted ten-fold
