  7. Density 2. Give the unit used to measure the following: liquid density g/mL

  8. Density 3. What is the density of a substance that has a volume of 12mL and a mass of 36g? D = m/V D = 36g / 12mL D = 3g/mL

  9. Density 4. A cube is 3cm on each side and has a mass of 54 grams. a. What is the volume of the cube? V = L x W x H V = 3cm x 3cm x 3cm V = 27cm3

  10. Density 4. A cube is 3cm on each side and has a mass of 54 grams. a. What is the density of the cube? D = m / V D = 54g / 27cm3 D = 2 g/cm3

  11. Density 5. A marble is lowered into a graduated cylinder holding 10mL of water. After the marble is added, the water level line rises to 12 mL. The marble has a mass of 6g. a. What is the volume of the marble? V= 12mL – 10mL V = 2mL 1cm3 = 1mL So… V = 2cm3

  12. Density 5. A marble is lowered into a graduated cylinder holding 10mL of water. After the marble is added, the water level line rises to 12 mL. The marble has a mass of 6g. a. What is the density of the marble? D = m / V D = 6g / 2cm3 D = 3 g/cm3
