Chapter 18, Problem 37AE

Interpretation Introduction

Interpretation:

Number of half-lives are required to change $96\text{ g}$ of sample of radioactive isotope to $1.5\text{ g}$ over approximately 24 days has to be determined. Also, approximate half-life of this isotope has to be determined.

Concept Introduction:

Half-life is time duration when concentration of reactant is reduced to half of its initial concentration. It is represented by $t_{\text{1/2}}$.
