▶ Practice Exercise 1You are asked to determine the mass of a piece of copper using itsreported density, 8.96 g/mL, and a 150-mL graduated cylinder.First, you add 105 mL of water to the graduated cylinder; thenyou place the piece of copper in the cylinder and record a volumeof 137 mL. What is the mass of the copper reported with the correctnumber of significant figures? (a) 287 g (b) 3.5 * 10-3 g/mL(c) 286.72 g/mL (d) 3.48 * 10-3 g/mL
Experimental Procedure Graphing
1.
Obtain a 100 mL graduated cylinder. Add 10.0 mL of the liquid to be analyzed to the cylinder and obtain the mass. Write this mass on the results table. NOTE: it does not have to be exactly 10.0 mL. If something other than 10.0 mL is added, note that change on the data table.
2.
Continue to add 10mL portions of liquid to the cylinder and obtain the mass each time. Write the cumulative volume, making sure to measure your total volume accurately with each addition, and its corresponding mass in the table. DO NOT EMPTY THE CYLINDER BETWEEN ADDITIONS OF LIQUID.
3.
Dispose of the liquid in the appropriate container in the fume
-hood.
4.
Draw a graph of mass versus volume. Use the guidelines set forth in the example. Make sure the graph takes up as much of the graph paper as possible
