The table below provides the half-lives of different radioisotopes.

| Radioisotope | Half-life (min) |
|---------------|-----------------|
| argon-44 | 12 |
| lead-196 | 37 |
| potassium-44 | 22 |
| indium-117 | 43 |

The question posed is: How long would it take, in minutes, for the amount of argon-44 to decrease from 64.0 mg to 8.00 mg?

The table shows four radioisotopes with their corresponding half-lives, indicating the time it takes for half of a sample of the isotope to decay. The task is to determine the time required for argon-44, which has a half-life of 12 minutes, to reduce in mass from 64.0 mg to 8.00 mg.
