Question

What is the half life of an isotope that has a decay constant of 0.00567?

Answer 1

We are asked to determine the half-life of an isotope. To do that we will use the following formula:

$T=\frac{ln(2)}{\lambda}$

Where:

$\begin{gathered} T=\text{ half-life} \\ \lambda=\text{ decay constant} \end{gathered}$

Now, we plug in the values:

$T=\frac{ln(2)}{0.00567}$

Solving the operations:

$T=122.25$

Therefore, the half-life is 122.25
