2. Can you determine the precision of measurement of the volume delivered by the pipet by doing the PROCEDURE A (Steps 1-5) only one time? Explain. PROCEDURE A. Calibration of Volumetric Pipet and Graduated Cylinder. (You will make 3 trials to test reproducibility of your data.) Step 1 Weigh a clean, dry 10mL or 25mL graduated cylinder as accurately as possible. (NOTE: Handle the graduated cylinder with crucible tongs to avoid contaminating it with oil or moisture from your fingers.) Record the mass of the cylinder on the REPORT FORM. C A UTON Always use a suction bulb to fill a pipet. Step 2 (See Techniques Section C) Use a 10mL volumetric pipet and bulb to carefully pipet 10mL of distilled water into the weighed graduated cylinder. (NOTE: Allow the pipet to drain for 20sec onds after the liquid stops flowing. Then touch the tip to the side of the cylinder wall. Do not blow the liquid out of the pipet!!) Step 3 Read and record the volume of liquid in the graduated cylinder on the REPORT FORM. Step 4 Weigh the graduated cylinder and water as accurately as possible. Record the mass on the REPORT FORM. Step 5 Measure the temperature of water and record the value on the REPORT FORM. Step 6 Dry the graduated cylinder and repeat Steps 1 through 5 to test the reproducibility of your data. Record these data as Trial 2. Step 7 Use the following density table for water to calculate the volume of water that was delivered by the pipet. How does the calculated volume delivered by the pipet compare to the
