  1. Wake-up Show all work using the following information to convert. 1 quark=2.9 who 1 who=5 mabees 1 bug = 3.7 quark 1 kuz = 3.2 mabees • 4.5 bug to quark • 3.3 mabeesto quark

  2. Density

  3. Which container is more dense? Container A has more particles therefore is more dense; takes up more volume than B A B

  4. What is Density? The relationship between the mass of asubstance and how much space it takes up (volume).

  5. Density Formula Units Density = Mass = grams = grams Volume cm3 mL

  6. Density Triangle Mass Volume Density = Mass = Density x Volume Mass Density Volume =

  7. Example #1 Some liquid nitrogen has a mass = 14 grams and a volume = 36.3 mL. What is the density? Density =Mass = 14 grams = 0.386 g/mL Volume 36.3 mL

  8. Example #2 A sample of wood has a mass of 58g and a volume of 73cm3. What is the wood’s density? 58g 73cm3 = 0.79g/cm3

  9. Example #3 The density of gold is 19.3g/cm3. What would the volume be fore a 180g sample of gold? 180g 19.3g/cm3 V = M D = 9.32 cm3

  10. Example #4 The density of steel is 7.8g/mL. What would the mass be for a 14mL sample of steel? (7.8g/mL)(14mL) M = D x V = 109.2g

  11. Example #5 A substance has a mass of 24.32kgand a volume of 19.8L. What is the density? 24.32 kg = 24,320 grams 19.8 L = 19, 800 mL D =Mass = 24,320 g = 1.23 g/mL Volume 19,800 mL

  12. Lab Practice Problem An unknown metal having a mass of 400 g was added to a graduated cylinder that contained 40 ml of water. After the addition, the water rose to 78.1 ml. Using this info and a reference table, identify the unknown metal. • Mass = ______ g • Volume = 78.1 ml – 40 ml = _____ ml • D = Mass Volume • Identity of metal = ____________ 400 38.1 400 g___ = 10.5g/mL 38. 1 mL Silver
