![### Educational Transcription
**Problem Statement:**
The temperature of a sample of copper increased by 24.7°C when 257 J of heat was applied. What is the mass of the sample?
\[ m = \_\_\_\_\_\_ \, \text{g} \]
**Table: Specific Heat Capacities**
| Substance | Specific Heat (J/g·°C) |
|-----------|-------------------------|
| Lead | 0.128 |
| Silver | 0.235 |
| Copper | 0.385 |
| Iron | 0.449 |
| Aluminum | 0.903 |
**Explanation:**
The problem involves calculating the mass of a copper sample based on its temperature change, the amount of heat applied, and its specific heat capacity. The provided table lists the specific heat capacities of various substances, which indicates how much heat (in Joules) is required to raise the temperature of 1 gram of the substance by 1°C. Here, the specific heat capacity of copper is crucial for solving the problem.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb1d14486-aab8-45fa-9185-3d15b7af8b4b%2F84aa5b05-81b1-4aad-8cf6-7c52ed717769%2Fasq9w5c_processed.png&w=3840&q=75)
