Chapter 5, Problem 5.104PAE

Interpretation Introduction

Interpretation: Number of lead atoms present in active space of lungs should be determined.

Conceptual Introduction:

Density is defined as mass per unit volume. Number of moles can be related to mass as follows:$\text{n=}\frac{\text{m}}{\text{M}}$

Here, m is mass and M is molar mass.

In 1 mole of a substance there are $6.023\times {10}^{23}$ atoms. This is known as Avogadro’s number.

Solutions: $\text{9}{\text{.95×10}}^{\text{11}}$ atomsof lead.
