Chapter 5, Problem 35P

Interpretation Introduction

Interpretation:

Molecules of oxygen in the lungs should be calculated with 1.1 atm and 37 ° C if the air contains 21% oxygen with the average pair of lungs has a volume of 5.5 L.

Concept Introduction:

The ideal gas equation is as follows:

$PV=nRT$

Here, p is the pressure, v is the volume, n is the number of moles, r is the gas constant and t is the temperature.

Also, number of moles of gas is related to mass and molar mass as follows:

$n=\frac{m}{M}$

Here, m is mass and m is molar mass.
