**1. Steps to Use the Half-Life Calculator:**

**Enter Initial Quantity**: Input the initial quantity of the substance into the "Initial Quantity" field.**Provide Half-Life**: Enter the half-life of the substance in the "Half-Life (in time units)" field.**Specify Number of Half-Lives**: Input the number of half-lives elapsed in the "Number of Half-Lives" field.**Calculate Remaining Quantity**: Click on the "Calculate Remaining Quantity" button to compute the remaining quantity of the substance.**View Result**: The calculated remaining quantity after the specified number of half-lives will be displayed below the input fields.

**2. About the Half-Life Calculator:**

**Purpose**: The Half-Life Calculator is a tool designed to determine the remaining quantity of a substance after a given number of half-lives.**Functionality**: It calculates the remaining quantity using the formula: Remaining Quantity=Initial QuantityĆ(0.5)Number of Half-LivesRemaining Quantity=Initial QuantityĆ(0.5)Number of Half-Lives.**Input Validation**: The calculator ensures that valid positive values are entered for the initial quantity, half-life, and number of half-lives.**Accuracy**: It provides the remaining quantity with precision, rounded to two decimal places.

**4. Benefits of Using the Half-Life Calculator:**

**Accuracy**: Offers precise calculations based on the half-life of the substance.**Convenience**: Provides a quick and easy-to-use tool for determining remaining quantities after a specified number of half-lives.**Educational Value**: Helps users understand the concept of half-life and its application in predicting decay.**Time-Saving**: Saves time compared to manual calculations, especially for multiple half-life scenarios.

**5. FAQ (Frequently Asked Questions):**

**Q: What is half-life?**- A: Half-life is the time required for a substance to decay to half of its initial quantity.

**Q: Can I input negative values for the initial quantity or half-life?**- A: No, the calculator only accepts positive values for the initial quantity and half-life.

**Q: What happens if I input zero for the initial quantity or half-life?**- A: The calculator will prompt you to enter valid positive values for these parameters.

**Q: Can I calculate the remaining quantity for fractional half-lives?**- A: Yes, you can input fractional values for the number of half-lives to calculate the remaining quantity accordingly.
