Physical Properties
Mass, Volume, and Density
Mass
What do you know about mass?
Mass
• Measure of the amount of matter that
makes up an object.
• Units used to designate mass are
kilograms (kg)
• You can measure an objects mass using a
balance (triple beam, electronic, spring).
Volume
What is Volume?
Volume
• Volume is a measurement of the threedimensional space occupied by an object.
• Units include cm3 and mL.
• Solids, liquids, and gases all have volume,
but you measure each differently.
– Solid – calculate geometrically or displacement
– Liquid – measure using a graduated cylinder
Density
How does Density relate to Mass
and Volume?
Density
• The amount of matter in a given space.
– Does this sound familiar?
• Concentration or Compactness
• The unit for density is
or
.
Mass, Volume, and Density
•
Mass volume and density are directly related.
Practice Exercise:
1. Measure the mass and volume of an object in the
room.
2. Calculate the Density of the Object.
3. What are the units associated with this
calculation?
Formulae
Density = Mass / Volume
Mass = Density x Volume
Volume = Mass / Density
Practice Problems
1. Calculate the volume of an object that is 34
cm by 25 cm by 8 cm.
2. Given:
V = 50 mL
Calculate: Mass
D = .75 g/mL
3. Given:
M = 55 g
Calculate: Volume
D = 2.3 g/cm3
4. Given:
M = .13 kg
Calculate: Density
V = 20 mL
