Chapter 2, Problem 98A

(a)

Interpretation Introduction

Interpretation:

The substance with greatest density needs to be determined.

Concept introduction:

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Answer to Problem 98A

Mercury has a greatest density.

Explanation of Solution

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample. From the given figure, mercury has the greatest density. The density of the mercury is approximately y $\text{14}{\text{g/cm}}^{\text{3}}$.

(b)

Interpretation Introduction

Interpretation:

The substance with least density needs to be determined.

Concept introduction:

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample.

y $\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Answer to Problem 98A

Wood has a lowest density.

Explanation of Solution

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample. From the given figure, wood has a lowest density. The density of wood is approximately $\text{0}\text{.2}{\text{g/cm}}^{\text{3}}$.

(c)

Interpretation Introduction

Interpretation:

The substance with density $\text{7}\text{.87}{\text{g/cm}}^{\text{3}}$ needs to be determined.

Concept introduction:

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Answer to Problem 98A

Iron has a density of $\text{7}\text{.87}{\text{g/cm}}^{\text{3}}$.

Explanation of Solution

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample. From the given figure, the substance with density of $\text{7}\text{.87}{\text{g/cm}}^{\text{3}}$ is iron.

(d)

Interpretation Introduction

Interpretation:

The substance with density $\text{11}\text{.4}{\text{g/cm}}^{\text{3}}$ needs to be determined.

Concept introduction:

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Answer to Problem 98A

Lead has a density of $\text{11}\text{.4}{\text{g/cm}}^{\text{3}}$.

Explanation of Solution

Density of a sample of matter or an object is equal to the mass of the sample divided by the volume of the sample. From the given figure, the substance with density of $\text{11}\text{.4}{\text{g/cm}}^{\text{3}}$ is lead.
