A student investigated the electrolysis of copper sulfate solution. During the process, copper is deposited at the negative electrode. The table below shows the mass of copper produced over time.
| Time (minutes) | Mass of copper (g) |
|---|---|
| 0 | 0.00 |
| 10 | 0.08 |
| 20 | 0.16 |
| 30 | 0.24 |
| 40 | 0.32 |
| 50 | 0.40 |
Assuming the rate of deposition of copper remains constant, determine the mass of copper that would be produced after 25 minutes.
