Chapter 4.4, Problem 4.12YT

(a)

Interpretation Introduction

Interpretation:

Molar mass of ozone has to be determined.

Concept Introduction:

Molar mass of a substance is the mass in grams of one mole of the substance. Unit of molar mass is g/mol.

Molar mass of $H_{2}O$ can be determined as follows,

$\text{Molar}\text{mass}\text{of}{\text{H}}_{\text{2}}\text{O}=\underset{MassoftwoHydrogen}{\left(\text{2}\text{×}\text{1}\text{g}\right)}\text{+}\underset{massofoneOxygen}{\left(\text{1×}\text{16}\text{g}\right)}=18g/mol$

(b)

Interpretation Introduction

Interpretation:

Molar mass of dinitrogen monoxide has to be determined.

Concept Introduction:

Molar mass of a substance is the mass in grams of one mole of the substance. Unit of molar mass is g/mol.

Molar mass of $H_{2}O$ can be determined as follows,

$\text{Molar}\text{mass}\text{of}{\text{H}}_{\text{2}}\text{O}=\underset{MassoftwoHydrogen}{\left(\text{2}\text{×}\text{1}\text{g}\right)}\text{+}\underset{massofoneOxygen}{\left(\text{1×}\text{16}\text{g}\right)}=18g/mol$

(c)

Interpretation Introduction

Interpretation:

Molar mass of $CC{l}_{3}F$ has to be determined.

Concept Introduction:

Molar mass of a substance is the mass in grams of one mole of the substance. Unit of molar mass is g/mol.

Molar mass of $H_{2}O$ can be determined as follows,

$\text{Molar}\text{mass}\text{of}{\text{H}}_{\text{2}}\text{O}=\underset{MassoftwoHydrogen}{\left(\text{2}\text{×}\text{1}\text{g}\right)}\text{+}\underset{massofoneOxygen}{\left(\text{1×}\text{16}\text{g}\right)}=18g/mol$
