MASS
• Definition:– Quantity of matter– a measure of the amount of "stuff" in
something.
• Unit: grams (g) or kilograms (kg)

Mass (cont.)
• Mass is not measured in POUNDS--pounds are weight! (Weight is a force, but more about that later!)

Mass Measurement Tool
• Electronic balance

Volume
• How much space matter occupies
• Units: cm3 or ml 1 cm3 = 1 ml

Volume Measurement Tool #1
• Ruler (measured in centimeters)• Unit: cm3 (cm x cm x cm)
V = L x W x H

Volume Measurement Tool #2
• Water Displacement (unit: mL)
Final Level

Density
• Density is mass per unit of volume.
• Lead is (more or less) dense than styrofoam.
• A loaf of bread is (more or less) dense than a brick.

How to Calculate Density:
• Density: D=m/v• Units: g/mL or g/cm3
D =

Density
• The metric system was designed so that the density of water = 1 g/ cm3 or 1000 kg/m3
• DH20 =1 g/cm3

Think about it!
• A rock from the moon fell in the parking lot at Skyview. To determine its density, a brilliant student measured its mass (10.0g) using an electronic scale and determined its volume (5.0 mL) using water displacement. What is the density of this moon rock?
