Chapter 21.5, Problem 4PE

Interpretation Introduction

Interpretation: The mass and the half life of isotope of xenon produced in an explosion is given. The radioactivity of the isotope of xenon is to be stated in becquerels and millicuries.

Concept introduction: The rate constant is calculated by the formula,

$\text{Rate}\text{constant}=\frac{0.693}{\text{Half}\text{life}}$

The radioactivity of an isotope is calculated by the formula,

$\text{Radioactivity}=\text{Rate}\text{conctant}\times \text{Number}\text{of}\text{atoms}$

One bacquerel is equal to $\frac{1000}{3.7\times {10}^{10}}$ millicuries.

To determine: The radioactivity of the isotope of xenon in becquerels and millicuries.
