30. What is density? Mass? Volume? Density: the amount of matter, or mass, per unit volume Mass: the amount of matter an object has Volume: the amount of space an object occupies

31. Volume & Density D = mass volume OR M = DV

32. Example 1 What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 29.4 cm 3 ?

33. Example 2 A piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood?

34. Example 3 A cup of gold colored metal beads was measured to have a mass 425 grams. By water displacement, the volume of the beads was calculated to be 48.0 cm3. Given the following densities, identify which metal it is! Gold: 19.3 g/mL Copper: 8.86 g/mL Bronze: 9.87 g/mL

35. Example 4 What is the mass of a cylinder of lead that is 2.50 cm in diameter, and 5.50 cm long. The density of lead is 11.4 g/mL and the volume of a cylinder is 6.

36. Example 5

37. Partner Race!! A little aluminum boat (mass of 14.50 g) has a volume of 450.00 cm3. The boat is place in a small pool of water and carefully filled with pennies. If each penny has a mass of 2.50 g, how many pennies can be added to the boat before it sinks?
