Chapter 10, Problem 3SEPP

Interpretation Introduction

Interpretation:

The mass of air exhaled with each breath is to be calculated.

Concept introduction:

An ideal gas can be characterized by three state variables such as absolute pressure $P$, volume $V$, and absolute temperature $T$. The relation between them canbe deduced from kinetic theory, called the ideal gas equation.

The idealgas equation is represented as follows:

$PV=n\text{R}T$

Here, $P$ is the pressure, $V$ is the volume, $\text{R}$ $\left(0.0821\text{ L}\text{.atm/K}\text{.mol}\right)$ is the gas constant, $T$ is the temperature, and $n$ is thenumber of moles.

Mass is calculated as follows:

$\text{Number of moles}=\frac{\text{Mass}}{\text{Molar Mass}}$
