# The volume of the room in cubic meters and liters has to be given. Concept Introduction: Density: is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). Density = Mass Volume

Question
Chapter 1, Problem 54RGQ

(a)

Interpretation Introduction

## Interpretation: The volume of the room in cubic meters and liters has to be given.Concept Introduction:Density: is a characteristic property of a substance.  The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).  Density = MassVolume

(a)

Expert Solution

Volume in liters is 65.41×103 L

### Explanation of Solution

The volume of the room in cubic meters and litres is given,

Calculate the volume of room:_Volume of a room is l×h×w  Given: length = 18ft = 5.4864m ,            wide = 15 ft = 4.572 m,            height = 8 ft 6 in = 2.5904 mVolume  = 5.49 m ×4.6 m ×2.59 m = 65.41m3Conversion of units:_Given: Volume = 65.41m3Known: 1 m3 = 103 LWhereas,65.41m3 is  = 65.41m3×103 L1 m3=65.41×103 L             =65.41×103 L.

The volume in cubic liters is 65.41×103 L

Expert Solution

Mass of air in kilogram is 78.492 Kg and in pounds is 0.1730 pounds.

### Explanation of Solution

The mass of air is calculated as,

Calculate the mass of air:_Given: Density = 1.2 g/L ; Volume = 65.41×103 LKnown: Density = MassVolumeWhereas,Mass = Density×Volume   = 1.2 g/L× 65.41×103 L  =78.492×103g.Conversion of units:_Known:1g = 0.001 kgWhereas, 78.492×103g is,(78.492×103g)(0.001 kg)1g = 78.492 Kg.Conversion of units:_Known:1g = 0.00220462 poundWhereas, 78.492×103g is,(78.492×103g)(0.00220462 pound)1g = 0.1730 pounds.

The obtained mass in kilograms and pounds are shown above.
