Chapter 7, Problem 51P

Interpretation Introduction

Interpretation:

The number of moles and molecules of air present in the lungs needs to be determined when the occupied volume is 5.0L at $37°\text{C}$ and pressure 740mmHg.

Concept introduction:

The concept of an ideal gas will be used. This is represented as

  $n=\frac{PV}{RT}$

Here,

n = number of moles

P = pressure

V = volume

R = gas constant

T = temperature

One mole of air contains $6.02\times {10}^{23}$ molecules.
