As a result, the solution is 25 days.

First-order kinetics govern radioactive decay.

And we know that the half-life of a first-order reaction is independent of the amount of sample used at the start.

A first-order reaction has a half-life of 0.693/K, where K is the reaction constant.

As a result, half of a 25g sample will deteriorate after 25 days ( same as 1g sample).

As a result, the solution is 25 days.

Phosphorus is a mineral found in a variety of foods and can also be obtained as a supplement. It has a number of roles in the body. It plays an essential role in the formation of bones, teeth, and cell membranes. It promotes enzyme activation and keeps blood pH within normal limits.
