Chapter 5, Problem 5.89P

Interpretation Introduction

(a)

Interpretation:

The mass of ${\text{CO}}_2$ in grams should be determined which is formed from 2.5 mole of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$ in the combustion reaction of acetylene.

Concept Introduction:

The number of moles of a compound is defined as the ratio of a given mass of the compound to the molar or molecular mass of the compound.

The mathematical expression is given by:

Number of moles = $\frac{\text{given mass of the compound}}{\text{molar mass of the compound}}$

Mass of compound can be calculated by below formula:

Mass = $\text{Number of moles }\times \text{ molar mass of compound}$

Interpretation Introduction

(b)

Interpretation:

The mass of ${\text{CO}}_2$ in grams should be determined which is formed from 0.50 mole of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$ in the combustion reaction of acetylene.

Concept Introduction:

The number of moles of a compound is defined as the ratio of a given mass of the compound to the molar or molecular mass of the compound.

The mathematical expression is given by:

Number of moles = $\frac{\text{given mass of the compound}}{\text{molar mass of the compound}}$

Mass of compound can be calculated by below formula:

Mass = $\text{Number of moles }\times \text{ molar mass of compound}$

Interpretation Introduction

(c)

Interpretation:

The mass of ${\text{H}}_2\text{O}$ in grams should be determined which is formed from 0.25 mole of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$ in the combustion reaction of acetylene.

Concept Introduction:

The number of moles of a compound is defined as the ratio of a given mass of the compound to the molar or molecular mass of the compound.

The mathematical expression is given by:

Number of moles = $\frac{\text{given mass of the compound}}{\text{molar mass of the compound}}$

Mass of compound can be calculated by below formula:

Mass = $\text{Number of moles }\times \text{ molar mass of compound}$

Interpretation Introduction

(d)

Interpretation:

The mass of ${\text{O}}_2$ in grams should be determined which reacts with3.0 mole of ${\text{C}}_{\text{2}}{\text{H}}_{\text{2}}$ in the combustion reaction of acetylene.
