  3. Daily Warm-Ups November 2011 Week #1 • The data table to the right shows the density of four different mineral samples. If a student accurately measured the mass of a sample of one of the four minerals to be 77.52 grams and its volume to be 10.2 cubic centimeters. Which mineral sample did the student measure? a. corundum b. galena c. hematite d. quartz

  4. Daily Warm-Ups November 2011Week #1 • A rectangular object has the following dimensions: Length = 15 cm, Width = 5 cm, Height = 2 cm. The object has a mass of 450 grams. What is its density? • A rock, when put into a graduated cylinder, raises the water level from an original level of 40 mL, to 47 mL. It has a mass of 35 grams. What is the rock’s density? (Hint: 1 mL = 1 cm3)

  5. Daily Warm-Ups November 2011Week #1 • An empty 250 mL beaker has a mass of 100 grams. When 100 mL of oil is added to the beaker, the total mass is 180 grams. What is the density of the oil in g / mL? • An unknown substance has a mass of 50 grams, and a volume of 25 cm3. What is the density of the substance? Will the substance sink or float in water?
