Chapter 8, Problem 75QRT

(a)

Interpretation Introduction

Interpretation:

(b)

Interpretation Introduction

Interpretation:

Volume of air inhaled in $24\text{ hr}$ and volume of air in a residence hall has to be compared.

(c)

Interpretation Introduction

Interpretation:

Number of Oxygen molecules in the air breathed in one day has to be determined.

Concept Introduction:

Ideal gas Equation:

Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.

  $\text{PV = nRT}$

Here,

  n is the moles of gas

    P is the Pressure

  V is the Volume

    T is the Temperature

    R is the gas constant
