Chapter 8, Problem 21E

Interpretation Introduction

(a)

Interpretation:

The mass in grams for a single particle of lithium $\text{Li}$ is to be calculated.

Concept introduction:

One mole of atoms, molecules or particles is defined as a quantity whose mass is equivalent to its gram atomic mass or molecular mass. One mole of any substance possesses fixed Avogadro’s number, which is equivalent to $\text{6}{\text{.022×10}}^{\text{23}}$ atoms.

Interpretation Introduction

(b)

Interpretation:

The mass in grams for a single particle of silicon $\text{Si}$ is to be calculated.

Concept introduction:

One mole of atoms, molecules or particles is defined as a quantity whose mass is equivalent to its gram atomic mass or molecular mass. One mole of any substance possesses fixed Avogadro’s number, which is equivalent to $\text{6}{\text{.022×10}}^{\text{23}}$ atoms.

Interpretation Introduction

(c)

Interpretation:

The mass in grams for a single particle of sulfur dioxide ${\text{SO}}_{\text{2}}$ is to be calculated.

Concept introduction:

One mole of atoms, molecules or particles is defined as a quantity whose mass is equivalent to its gram atomic mass or molecular mass. One mole of any substance possesses fixed Avogadro’s number, which is equivalent to $\text{6}{\text{.022×10}}^{\text{23}}$ atoms.

Interpretation Introduction

(d)

Interpretation:

The mass in grams for a single particle of nitrous oxide ${\text{N}}_{\text{2}}\text{O}$ is to be calculated.

Concept introduction:

One mole of atoms, molecules or particles is defined as a quantity whose mass is equivalent to its gram atomic mass or molecular mass. One mole of any substance possesses fixed Avogadro’s number, which is equivalent to $\text{6}{\text{.022×10}}^{\text{23}}$ atoms.
