Chapter 17, Problem 94E

Interpretation Introduction

Interpretation: The number of alpha emissions that occur in $6.0\text{ minutes}$ by $\text{Po-218}$ nucleus is to be calculated.

Concept Introduction:

Half-life time is the time in which parent nuclei reduced to half of its initial amount.

Alpha emission takes place when an unstable radioactive nucleus emits a particle containing 2 protons and 2 neutrons.

The molar mass of $\text{Po}$ is $209\text{ g}$.

One mole of an element is equal to $6.022\times {10}^{23}\text{ atoms}$.

One mole of any substance has a mass equal to its molar mass.
