Silver nitrate solution was electrolysed for ten minutes using silver electrodes.
Table 1 shows the mass of the anode and of the cathode before and after the electrolysis.
Table 1
| Anode | Cathode | |
|---|---|---|
| Mass of electrode before electrolysis / g | 3.84 | 3.50 |
| Mass of electrode after electrolysis / g | 3.12 | 4.18 |
Calculate the mass of silver deposited.
