Question

How long is 5 half lives if the half life is 2.6 hours? Remember to round to the correct number of significant figures and use units ( hours)

Answer 1

`\Delta t = 13\,h`

Step-by-step explanation:

Half time is period required to desintegrating the half of the initial number of atoms. Then, the total time is:

`\Delta t = 5\cdot (2.6\,h)`

`\Delta t = 13\,h`
