What unit would we use with our final volume measurement? 6. Describe/explain how we would measure the volume of a certain amount of water. 7. Describe/explain how we would measure the volume of a clothespin. 8. Describe/explain how we would measure the volume of a block of wood. 9. What is a good definition for density? 10. What is the equation for calculating density? What unit would we use with our final density measurement? Part Two: Practice Problems 11. Mercury metal fills a graduated cylinder that holds exactly 22.5 mL. This same amount of mercury has a mass of 306 g. Calculate the density of mercury. 12. A rectangular block of copper metal has a mass of 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. What is the density of copper? Density Study Guide 13. An object on the triple beam balance measured 21.6 grams. The object happened to be 14 cm long and 2 cm wide. When put in water, the water level rose 3 ml. What is the density of the object? 14. What is the liquid’s volume contained in this graduated cylinder? ___ 15. The graduated cylinder shown below contains a small mineral. Before the mineral was put into the graduated cylinder, the water level was at 71 mL. What is the volume of the mineral? ________ 16. Draw in water’s meniscus on this graduated cylinder if the cylinder contained a rock that had a volume of 11.5 mL and 51 mL of water.
