**Calorimetry Problem: Identifying a Metal by Its Specific Heat Capacity**

**Problem Statement:**

An 80.0 g sample of an unknown metal, initially at 96.0°C, is placed into 150.0 g of water at an initial temperature of 26.0°C in a calorimeter. After thermal equilibrium is reached, the final temperature of the water is 28.1°C. The objective is to determine the identity of the metal based on its specific heat capacity. The specific heat capacity of water is given as 4.18 J/g·°C.

| Metal      | Specific Heat Capacity (J/g·°C) |
|------------|----------------------------------|
| Aluminum   | 0.90                             |
| Copper     | 0.38                             |
| Iron       | 0.45                             |
| Magnesium  | 1.00                             |
| Silver     | 0.23                             |
| Tin        | 0.32                             |
| Titanium   | 0.52                             |

**Task:**

Using the data provided and the principle of conservation of energy in calorimetry, calculate the specific heat capacity of the unknown metal. Compare the calculated value with the values in the table to identify the metal.
