- 15. A solid compound has a mass of 52.20 g. You scrape 14.85 g worth of material off the compound for testing. What percentage of compound is left over?arrow_forwardThe volume of an irregularly shaped solid can be determined by immersing the solid in a liquid and measuring the volume of liquid displaced. Find the volume and density of the following: a. An irregular piece of the mineral quartz is found to weigh 12.4 g. It is then placed into a graduated cylinder that contains some water. The quartz does not float. The water in the cylinder was at a level of 25.2 mL before the quartz was added and at 29.9 mL afterward. The volume of a sample of lead shot is determined using a graduated cylinder, as in part (a). The cylinder readings are 16.3 mL before the shot is added and 21.7 mL after. The sample of shot weighs 61.0 g.arrow_forwardA. Liquids are moved from one container to another using a pipette, droppers, and volumetric flasks.B.
