5
Mass

• Amount of matter in an object
• Mass is measured with a triple beam balance
• Grams is the basic unit of mass
• Weight is not Mass because weight is affected by
  gravity.
• Practice Problem 1500g ____ kg

6
Volume

• Is the amount of space an object
• occupies
• If its a solid cm3. If its a liquid mL
• Solid Calculate LxWxH
• Liquid Grad. Cylinder

Density

• Heaviness of objects. Compare a rock to a
  crumbled piece of paper. The rock is more dense
  than the paper.
• Formula for Density Mass/Volume
• Practice Problem Calculate the density in g/mL
  of aluminum if a 50 mL block weighs135 g.
