Mass Measure
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 three-dimensional 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 Problems1. Calculate the volume of an object that is 34
cm by 25 cm by 8 cm.
2. Given: V = 50 mL D = .75 g/mLCalculate:Mass
3. Given: M = 55 g D = 2.3 g/cm3
Calculate: Volume
4. Given: M = .13 kg V = 20 mLCalculate:Density
