# The pressure given should be converted into the units of atmosphere. Concept Introduction: Pressure = Force Area Pressure can be expressed in different units. But it is normally reported in mm Hg ( millimeters of mercury ) General unit conversions: 1 atm = 760 mm Hg 1 pascal = 1 newton / meter 2 1 atm = 760 mm Hg = 101 .325 kilopascals = 1 .01325 bar 1 bar = 1×10 5 pascal ### Chemistry & Chemical Reactivity

#### Solutions

Chapter 10, Problem 1PS

(a)

Interpretation Introduction

## Interpretation:The pressure given should be converted into the units of atmosphere.Concept Introduction:  Pressure = ForceAreaPressure can be expressed in different units. But it is normally reported in mm Hg (millimeters of mercury)General unit conversions:  1 atm = 760 mm Hg1 pascal = 1 newton/meter21 atm = 760 mm Hg = 101.325 kilopascals = 1.01325 bar1 bar = 1×105 pascal

Expert Solution

440mmHg=0.578atm

### Explanation of Solution

The given pressure are in the units of atmosphere

Given the value of pressure as 440mmHg

Conversion into atm:

1atm=760mmHg440mmHg×1atm760mmHg=0.578atm

(b)

Interpretation Introduction

### Interpretation:The pressure given should be converted into the units of bars.Concept Introduction:  Pressure = ForceAreaPressure can be expressed in different units. But it is normally reported in mm Hg (millimeters of mercury)General unit conversions:  1 atm = 760 mm Hg1 pascal = 1 newton/meter21 atm = 760 mm Hg = 101.325 kilopascals = 1.01325 bar1 bar = 1×105 pascal

Expert Solution

440mmHg=0.586bar

### Explanation of Solution

The given pressure are in the units of bar

Given the value of pressure as 440mmHg

Conversion into bar:

440mmHg×1.013bar760mmHg=0.586bar

(c)

Interpretation Introduction

### Interpretation:The pressure given should be converted into the units of kilopascals.Concept Introduction:  Pressure = ForceAreaPressure can be expressed in different units. But it is normally reported in mm Hg (millimeters of mercury)General unit conversions:  1 atm = 760 mm Hg1 pascal = 1 newton/meter21 atm = 760 mm Hg = 101.325 kilopascals = 1.01325 bar1 bar = 1×105 pascal

Expert Solution

440mmHg=58.6kPa

### Explanation of Solution

The given pressure are in the units of kilopascals.

Given the value of pressure as 440mmHg

Conversion into kilopascals:

440mmHg×101.3kPa760mmHg=58.6kPa
