If the average life period of a specific radioactive substance is calculated to be , what is the exa — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

The relationship between average life ($T$) and half-life ($T_{1/2}$) is $T = 1.44 \times T_{1/2}$. Given that the average life $T = 144\text{ days}$, we have $144 = 1.44 \times T_{1/2}$. Solving for half-life yields $T_{1/2} = 144 / 1.44 = 100\text{ days}$.
