Chapter 19, Problem 49E

Interpretation Introduction

Interpretation:

Half-life of radium- $226$ is given. The volume of radon gas produced by $\text{25}\text{.0}\text{g}$ of radium in $\text{5}\text{.0}\text{days}$ is to be calculated.

Concept introduction:Decay constant is the quantity that expresses the rate of decrease of number of atoms of a radioactive element per second. Half life is defined as the time required for the number of nuclides to reach half of the original value.

To determine:The volume of radon gas produced by $\text{25}\text{.0}\text{g}$ of radium in $\text{5}\text{.0}\text{days}$ .
