![### Galvanic Cell Experiment with Metal M
**Objective:**
To determine the positive electrode and the voltage in a galvanic cell setup using a metal \( M \) that forms a soluble sulfate salt \( M_2(SO_4)_3 \).
**Setup:**
- Two half cells are used in the apparatus.
- The left half cell is filled with a 5.00 M solution of \( M_2(SO_4)_3 \).
- The right half cell is filled with a 250 mM (0.250 M) solution of the same metal sulfate \( M_2(SO_4)_3 \).
- Electrodes made of metal \( M \) are placed into both solutions.
- A voltmeter is connected between the two electrodes.
- The temperature of the apparatus is kept constant at 35.0°C.
**Questions:**
1. **Which electrode will be positive?**
- \( \circ \) Left
- \( \circ \) Right
2. **What voltage will the voltmeter show?** Assume its positive lead is connected to the positive electrode.
- \( [ \text{Enter value here} ] \)
- Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffb7c8d89-d88e-4012-9dce-44cfff81e849%2Fd55aa148-4a26-4dfe-9add-f0ce18ed2920%2F1r2zhyf_processed.jpeg&w=3840&q=75)
