Chapter 2, Problem 88QAP

For the masses and volumes indicated, calculate the density in grams per cubic centimeter.

  1. mass = 4.53 kg; volume = 225 cm3
  2. mass = 26.3 g; volume = 25.0 mL
  3. mass = 1.00 lb; volume = 500. cm3
  4. mass = 352 mg; volume = 0.27 1 cm3

Interpretation Introduction

Interpretation:

The density in grams per cubic centimeter for the mass 4.53 kg and volume 225 cm3 should be determined.

Concept Introduction:

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume.

Answer to Problem 88QAP

The density in grams per cubic centimeter for the mass 4.53 kg and volume 225 cm3 is 20.13 g/cm3.

Explanation of Solution

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume

Mass = 4.53 kg (given)

Since, 1 kg = 1000 g

So, 4.53 kg = 4.53 * 1000 = 4530 g

Substituting the values:

Density = 4530 g225 cm3 Density = 20.13 g/cm3.

Interpretation Introduction

Interpretation:

The density in grams per cubic centimeter for the mass 26.3 g and volume 25.0 mLshould be determined.

Concept Introduction:

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume.

Answer to Problem 88QAP

The density in grams per cubic centimeter for the mass 26.3 g and volume 25.0 mL is 1.052 g/cm3.

Explanation of Solution

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume

Volume = 25.0 mL (given)

Since, 1 mL = 1 cm3

So, 25.0 mL = 25.0 cm3

Substituting the values:

Density = 26.3 g25.0 cm3 Density = 1.052 g/cm3.

Interpretation Introduction

Interpretation:

The density in grams per cubic centimeter for the mass 1.00 lb and volume 500 cm3 should be determined.

Concept Introduction:

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume.

Answer to Problem 88QAP

The density in grams per cubic centimeter for the mass 1.00 lb and volume 500 cm3 is 0.908 g/cm3.

Explanation of Solution

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume

Mass = 1.00lb (given)

1 lb = 453.592 g

Substituting the values:

Density = 453.592 g500 cm3 Density = 0.908 g/cm3.

Interpretation Introduction

Interpretation:

The density in grams per cubic centimeter for the mass 352 mg and volume 0.271 cm3 should be determined.

Concept Introduction:

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume.

Answer to Problem 88QAP

The density in grams per cubic centimeter for the mass 352 mg and volume 0.271 cm3 is 1.299 g/cm3.

Explanation of Solution

The ratio of mass to volume of a substance is said to be the density of a substance. The formula is:

Density = massvolume

Mass = 352 mg (given)

Since, 1 mg = 0.001 g

So, 352 mg = 352 × 0.001 = 0.352 g

Substituting the values:

Density = 0.352 g 0.271 cm3Density = 1.299 g/cm3.
