Question
**Zinc Concentration Cell Problem**

The voltage generated by the zinc concentration cell described by the line notation is given as:

\[ \text{Zn(s) | Zn}^{2+}(\text{aq, 0.100 M}) \, \| \, \text{Zn}^{2+}(\text{aq, ? M}) | \text{Zn(s)} \]

The cell generates a voltage of 10.0 mV at 25°C. Your task is to calculate the concentration of the \(\text{Zn}^{2+}(\text{aq})\) ion at the cathode.

**Concentration Calculated:**

- Attempted Concentration: 0.018 M
- Status: Incorrect

This example illustrates the process of using electrochemical cell line notation and the relationship between concentration and voltage to determine unknown parameters in concentration cells.
