This tool calculates how much of a substance will remain after a certain period based on its decay rate.

## How to Use the Decay Calculator

The Decay Calculator helps you calculate the final amount of a substance after a certain period of time, given the initial amount, the decay constant, and the time elapsed. You need to input three values:

**Initial Amount (N0)**: The amount of substance at the initial time (t=0).**Decay Constant (λ)**: The decay constant, which is a positive number representing the rate of decay.**Time (t)**: The time period over which the decay occurs.

Click the “Calculate” button to see the final amount (N) after the given time period.

## How It Works

The decay calculation is based on the exponential decay formula:

`N = N0 * e^(-λt)`

Where:

**N**is the final amount after time`t`

.**N0**is the initial amount.**λ**is the decay constant.**t**is the time period.

The formula uses the base of the natural logarithm (e ≈ 2.71828).

## Limitations

This calculator assumes a constant decay rate and does not account for factors such as changes in environmental conditions that may affect the decay rate. The values provided should be used for estimation purposes and not for precise scientific calculations.
