![**Calorimetry Experiment: Determining the Specific Heat Capacity of Iron**
In this experiment, a 60.0 g sample of iron is placed into a calorimeter, which contains 300.0 g of water. Initially, the iron sample is at a temperature of 98.3 °C, while the water starts at 22.0 °C. After heat exchange, the final temperature of the water stabilizes at 24.1 °C. The pressure throughout the experiment is maintained at 1 atm.
**Objective:**
Calculate the specific heat capacity of iron based on the results of the experiment. Ensure that your answer is rounded to the appropriate number of significant digits.
**Diagram Explanation:**
- **Thermometer:** Measures the temperature within the calorimeter.
- **Insulated Container:** Ensures minimal heat exchange with the environment, allowing for more accurate measurement of heat transfer between the iron and water.
- **Water:** The medium that absorbs heat from the iron sample.
- **Sample:** The iron sample whose specific heat capacity is to be determined.
- **Calorimeter Setup:** The entire setup, consisting of an insulated container and a thermometer, is arranged to facilitate effective heat transfer analysis.
The graph provided for input appears to be an area where the calculated specific heat capacity can be entered, typically showing units in Joules per gram per degree Celsius (J/g·°C).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdf160487-cd07-498e-ac49-eb7d4eed62da%2Fc0b16626-e537-41de-8189-842093302d9b%2Fu4oe328_processed.png&w=3840&q=75)
