Chapter 5, Problem 5.97P

(a)

Interpretation Introduction

Interpretation:

The mass of carbon dioxide and water should be determined which is exhaled in 1 h of sleep.

Concept Introduction:

Ideal gas law equation is shown as:

  $\text{PV= nRT}$

Where,

P = Pressure

V = Volume

n = Number of moles

R = Universal gas constant

T = Temperature

Number of moles is defined as the ratio of mass to the molar mass of the compound.

The mathematical expression is:

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

(b)

Interpretation Introduction

Interpretation:

The mass in grams should be determined of body which is lost by person in an 8-h sleep when all ${\text{CO}}_2$ and ${\text{H}}_{\text{2}}\text{O}$ exhaled comes from the metabolism of glucose.

  ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}{\text{(s)+6O}}_{\text{2}}\text{(g)}\to {\text{6CO}}_{\text{2}}{\text{(g)+6H}}_2\text{O(g)}$
