Chapter 2.7, Problem 2.87QAP

Interpretation Introduction

(a)

Interpretation:

The specific gravity of the sample should be calculated.

Concept Introduction:

Specific gravity can be defined as the ratio of density of the object and density of water. The mathematical expression for density is:

  $\text{Density (g/mL) = }\frac{\text{Mass (g)}}{\text{Volume (mL)}}$

Interpretation Introduction

(b)

Interpretation:

Concept Introduction:

Specific gravity can be defined as the ratio of density of the object and density of water. The mathematical expression for density is:

  $\text{Density (g/mL) = }\frac{\text{Mass (g)}}{\text{Volume (mL)}}$

Interpretation Introduction

(c)

Interpretation:

The mass in grams should be calculated.

Concept Introduction:

Specific gravity can be defined as the ratio of density of the object and density of water. The mathematical expression for density is:

  $\text{Density (g/mL) = }\frac{\text{Mass (g)}}{\text{Volume (mL)}}$

Interpretation Introduction

(d)

Interpretation:

The volume of solution used should be calculated.

Concept Introduction:

Specific gravity can be defined as the ratio of density of the object and density of water. The mathematical expression for density is:

  $\text{Density (g/mL) = }\frac{\text{Mass (g)}}{\text{Volume (mL)}}$
