Chapter 10, Problem 52A

(a)

Interpretation Introduction

Interpretation: To determine the number of hydrogen atoms in a given compound.

Concept Introduction: The molecular formula is the representation of the chemical proportion of a molecule by using the total number and symbol of the atoms present in the molecule.

Answer to Problem 52A

The number of hydrogen atoms will be 3.

Explanation of Solution

The given compound is $\text{Al}{\left(\text{OH}\right)}_{\text{3}}$

The total number of hydrogen atoms in $\text{Al}{\left(\text{OH}\right)}_{\text{3}}$= 3

(b)

Interpretation Introduction

Interpretation: To determine the number of hydrogen atoms in a given compound.

Concept Introduction: The molecular formula is the representation of the chemical proportion of a molecule by using the total number and symbol of the atoms present in the molecule.

Answer to Problem 52A

The number of hydrogen atoms will be 2.

Explanation of Solution

The given compound is ${\text{H}}_{\text{2}}{\text{C}}_{\text{2}}{\text{O}}_{\text{4}}$

The total number of a hydrogen atoms in ${\text{H}}_{\text{2}}{\text{C}}_{\text{2}}{\text{O}}_{\text{4}}$ =2

(c)

Interpretation Introduction

Interpretation: To determine the number of hydrogen atoms in a given compound.

Concept Introduction: The molecular formula is the representation of the chemical proportion of a molecule by using the total number and symbol of the atoms present in the molecule.

Answer to Problem 52A

The number of hydrogen atom will be 9.

Explanation of Solution

The given compound is ${\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{HPO}}_{\text{4}}$

The total number of hydrogen atom in ${\left({\text{NH}}_{\text{4}}\right)}_{\text{2}}{\text{HPO}}_{\text{4}}$ can be determined as:

Total number of hydrogens = $\text{9 (4}\times \text{2+1)}$

(d)

Interpretation Introduction

Interpretation: To determine the number of hydrogen atoms in a given compound.

Concept Introduction: The molecular formula is the representation of the chemical proportion of a molecule by using the total number and symbol of the atoms present in the molecule.

Answer to Problem 52A

The number of hydrogen atoms will be 10.

Explanation of Solution

The given compound is ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}\text{O}$

The total number of a hydrogen atom in ${\text{C}}_{\text{4}}{\text{H}}_{\text{10}}\text{O}$ = 10
