  1. Density Notes

  2. What is density? • Density = Mass/Volume • Different materials usually have different densities • Discovered by Archimedes • King Heiro’s goldsmith

  3. How to measure it • A homogeneous object= mass/volume • Mass measured with scale or balance • Volume measured directly or with displacement of water • Units of measurement: kg/m3 or kg/L

  4. Conversions • Density= mass/volume • Volume= mass/density • Mass= Density x volume

  5. Example 1 • If Spiderman has a mass of 90kg and has a volume of 30 liters, what is his density • Density= mass/volume • Density= 90kg/30L • Density= 3kg/L

  6. Example 2 • Today on Mount Everest, the air has a density of 75kg/L in a volume of 5 liters. What is the mass of the air? • Mass=Density x Volume • M= (75kg)(5L) • M= 375 kg

  7. Example 3 • The density of ascorbic acid is 130 kg/L and we have a total of 5 liters of the chemical. What is the mass? • M=DV • M= (130kg/L)(5 L) • M= 650 kg

  8. Example 4 • Ms. Zeidman’s brain has a mass of 28 kg and takes up a volume of 7 liters. What is the density of Ms. Zeidman’s brain? • D=M/V • D=28 kg/7L • D= 4kg/L

  9. Example 5 • The density of Ms. Newberg’s 7thhour class is 12,500 kg/L and the mass is 200,000 kg. What is the volume of the class? • V=M/D • V= 200,000kg/12,500 kg/L • V=16L

  10. Example 6 • Your table has a density of 750 kg/L and a mass of 100 kg. What is the volume of your table? • V=M/D • V=100kg/750kg/L • V=.13L
