**Cell Notation and Reduction Potentials**

In the cell notation:

\[ X_{(s)} | X^{3+} \, (1.93 \, \text{M}) || \text{MnO}_4^{-} \, (1.20 \, \text{M}) | \text{Mn}^{2+} \, (0.27 \, \text{M}) | \text{H}^+ \, (2.72 \, \text{M}) \]

- **Reduction Potentials:**
- The reduction potential for $ X^{3+} $ is 1.47 V.
- The reduction potential for $\text{MnO}_4^{-}$ is 1.51 V.

**Question:**
What is the potential of this non-standard cell (in Volts)?

Expert Solution

Step 1
