Chapter 14, Problem 24Ci

(a)

Interpretation Introduction

Interpretation : The volume percent of ethanol needs to be determined.

Concept Introduction : The volume percent or v/v is the way to express the concentration of solution. The mathematical expression for it is:

  $\text{Volume percent = }\frac{\text{Volume of substance }}{\text{total volume of solution }}\text{ x 100 }$

Fermentation is the reaction by which sugar molecules convert to alcohol and carbon dioxide. The reaction occurs in the limited supply or absence of oxygen gas.

(b)

Interpretation Introduction

Interpretation: The molarity of the ethanol needs to be determined.

Concept Introduction : The volume percent or v/v is the way to express the concentration of solution. The mathematical expression for it is:

  $\text{Volume percent = }\frac{\text{Volume of substance }}{\text{total volume of solution }}\text{ x 100 }$

Fermentation is the reaction by which sugar molecules convert to alcohol and carbon dioxide. The reaction occurs in the limited supply or absence of oxygen gas.

(c)

Interpretation Introduction

Interpretation : The balanced chemical reaction for fermentation of sugar needs to be determined.

Concept Introduction : The volume percent or v/v is the way to express the concentration of solution. The mathematical expression for it is:

  $\text{Volume percent = }\frac{\text{Volume of substance }}{\text{total volume of solution }}\text{ x 100 }$

Fermentation is the reaction by which sugar molecules convert to alcohol and carbon dioxide. The reaction occurs in the limited supply or absence of oxygen gas.

(d)

Interpretation Introduction

Interpretation : The mass of sugar obtained from grapes to produce 1 bottle of port wine needs to be determined.

Concept Introduction : The volume percent or v/v is the way to express the concentration of solution. The mathematical expression for it is:

  $\text{Volume percent = }\frac{\text{Volume of substance }}{\text{total volume of solution }}\text{ x 100 }$

Fermentation is the reaction by which sugar molecules convert to alcohol and carbon dioxide. The reaction occurs in the limited supply or absence of oxygen gas.

(e)

Interpretation Introduction

Interpretation : The number of bottles of port wine produced from given mass of grapes needs to be determined.

Concept Introduction : The volume percent or v/v is the way to express the concentration of solution. The mathematical expression for it is:

  $\text{Volume percent = }\frac{\text{Volume of substance }}{\text{total volume of solution }}\text{ x 100 }$

Fermentation is the reaction by which sugar molecules convert to alcohol and carbon dioxide. The reaction occurs in the limited supply or absence of oxygen gas.
