Chapter 5, Problem 50E

(a)

Interpretation Introduction

Interpretation: For the given situations the number of moles of air in human lungs should be determined

Concept introduction:

By combining the three gaseous laws namely Boyle’s law, Charles’s law and Avogadro’s law a combined gaseous equation is obtained. This combined gaseous equation is called Ideal gas law.

According to ideal gas law,

                                             $\text{PV=nRT}$

Where,

          P = pressure in atmospheres

          V= volumes in liters

          n = number of moles

          R =universal gas constant ( $0.08206L\cdot atm/K\cdot mol$)

          T = temperature in kelvins

By knowing any three of these properties, the state of a gas can be simply identified with applying the ideal gas equation.

Number of moles of gas can be calculated from the ideal gas equation is as follows,

$n=\frac{PV}{RT}$
