![### Exercise: Determining Specific Heat of an Unknown Metal
**Problem Statement:**
An unknown metal has a mass of 88.0 g. When 2440 J of heat are added to the sample, the sample temperature changes by 30.9 °C. Calculate the specific heat of the unknown metal.
**Calculation:**
- **Formula for Specific Heat:**
\[
\text{specific heat} (c) = \frac{q}{m \times \Delta T}
\]
where \( q \) is the heat added (2440 J), \( m \) is the mass (88.0 g), and \( \Delta T \) is the temperature change (30.9 °C).
- **Enter Specific Heat:**
\[ \text{specific heat:} \ \_\_\_\_\_\_\_\_\_ \ \text{J/(g} \cdot \text{°C)} \]
**Question:**
What is the possible identity of the metal based on the calculated specific heat?
- \( \circ \) aluminum
- \( \circ \) strontium
- \( \circ \) calcium
- \( \circ \) tin
**Reference Table:**
| Metal | Specific Heat (J/g·°C) |
|-----------|------------------------|
| aluminum | 0.897 |
| tin | 0.210 |
| strontium | 0.301 |
| barium | 0.204 |
| calcium | 0.650 |
**Note:** Compare the calculated specific heat with the values in the table to identify the metal.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F40712c57-682a-4e6d-8b2a-9b23b42b2459%2F89b80057-2624-4a0a-a326-502de73747bc%2Fthwlxnj_processed.png&w=3840&q=75)
