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: • Measure the mass and volume of an object in the room. • Calculate the Density of the Object. • What are the units associated with this calculation?
Formulae Density = Mass / Volume Mass = Density x Volume Volume = Mass / Density
Practice Problems • Calculate the volume of an object that is 34 cm by 25 cm by 8 cm. • Given: V = 50 mL D = .75 g/mL Calculate: Mass 3. Given: M = 55 g D = 2.3 g/cm3 Calculate: Volume • Given: M = .13 kg V = 20 mL Calculate: Density
