- 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.
