Chapter 19, Problem 41E

Interpretation Introduction

Interpretation: Half-life of bromine- $82$ nucleus is given. Mass of ${}^{82}\text{Br}$ required is $\text{1}\text{g}$ and the delivery time is $3$ days. Mass of $\text{NaBr}$ required to order is to be calculated.

Concept introduction: A process through which an unstable nuclide loses its energy due to excess of protons or neutrons is known as radioactive decay.

To determine: The mass of $\text{NaBr}$ need to be ordered to get $\text{1}\text{g}$ of ${}^{82}\text{Br}$.
