Three electrolytic cells containing aqueous $\mathrm{AgNO}{}_3$, aqueous $\mathrm{CuSO}{}_4$ and dilute $\mathrm{H}{}_2\mathrm{SO}{}_4$, all with platinum electrodes, are connected in series and $0.0500\mathrm{F}$ of charge is passed. Take Ag = 108, Cu = 63.5, molar volume at STP $=22.4\mathrm{L}$. Which statements are correct?

1. A$5.40\mathrm{g}$ of silver is deposited in the first cell
2. BAbout $1.59\mathrm{g}$ of copper is deposited in the second cell
3. C$560\mathrm{mL}$ of $\mathrm{O}{}_2$ at STP is liberated at the anode of the third cell
4. D$560\mathrm{mL}$ of $\mathrm{H}{}_2$ at STP is liberated at the cathode of the third cell
