Question
**Question 5**

A researcher is conducting thyroid studies using the radioisotope \(^{123}\text{I}\), which has a half-life of 13.3 hours.

**Diagram Explanation:**

- **Left Diagram (Time = 0):** 
  - Shows a 4x5 grid of circles, all of which represent the radioisotope \(^{123}\text{I}\). They are colored blue.

- **Right Diagram (Time = ?):**
  - Shows the same 4x5 grid, but most circles are now gray, indicating decay products. A few blue circles remain, representing the remaining \(^{123}\text{I}\).

**Questions:**

1. **How much time has elapsed for the process shown above?**
   - Answer: \_\_\_\_ h

2. **Determine the decay constant for \(^{123}\text{I}\).**
   - Answer: \_\_\_\_ h\(^{-1}\)

3. **Starting with 16.0 mg \(^{123}\text{I}\), how much of this radioisotope is left after 2.25 days?**
   - Answer: \_\_\_\_ mg
