Question
### Part A

**Problem Statement:**
A volume of 75.0 mL of H₂O is initially at room temperature (22.00°C). A chilled steel rod at 2.00°C is placed in the water. If the final temperature of the system is 21.00°C, what is the mass of the steel bar?

**Given Values:**
- Volume of water (H₂O): 75.0 mL
- Initial temperature of water: 22.00°C
- Initial temperature of steel rod: 2.00°C
- Final temperature of the system: 21.00°C
- Specific heat of water: 4.18 J/(g·°C)
- Specific heat of steel: 0.452 J/(g·°C)

**Requirement:**
Express your answer to three significant figures and include the appropriate units.

**Instructions:**
- Use the given values to calculate the mass of the steel bar.
- Make sure to input your answer with three significant figures.
- Click on "Submit" after entering your answer.

**Hints:**
Click "View Available Hint(s)" for guidance if needed.

**Input Section:**
- The answer should be filled in the provided space next to "mass of the steel = [Value] [Units]."

**Buttons for Input:**
- Two buttons are provided - one for symbols and one for units.
- Additionally, there are buttons for actions like backspace, enter, options, and help.

**Submit Button:**
- After entering your answer, click the "Submit" button.
