Question

Name Determining the Density of Liquid and Solid Substances ab 1. Should you use your bare fingers when handling a graduated cylinder, a rubber stopper and a piece of metal during this lab? If not, which tool should you use? 2. Name the method that is used in part IIl of this lab to determine the volume of a metal sample. 3. A test tube contains four liquid layers: chloroform, diethyl ether, mercury and water. Write a name of each layer on the sketch on the right. A marble with the density of 2.7 g/em) is dropped in the cylinder. Where will it rest (draw it)y? Substance Chloroform Diethyl ether Ethanol Mercury Toluene Water Density g/mL (at the room temperature) 1483 0.708 0.789 13.534 0.867 1.000 4. A student has measured the volume of an unknown liquid sample to be 5.50 ml. and its mass to be 4.32 g. What is the density of the liquid? Show your work Do not forget about the units and significant figures. Use the table above to identify the liquid. Density The liquid is 5. Someone sold you a ring and told you it was a gold one. Just to double check you decided to figure out its density. You weighed it and found the mass to be 21.25 g. The volume of the ring was measured by displacement. After it was placed in a graduated cylinder with 37.0 mL of water, the volume of water increased to 39.5 mL What is the density of the ring? Is it gold? The density 14K gold ranges form 12.6 to 14.2 g/cm2, that of 10K gold rages from 11.0 to 11.6 g/cm.
