Use the images provided below to collect data virtually. If you have technical issues with the virtual data, please contact support. Report your measurements to the correct number of significant figures. From the procedure 1. Record the number identifying the unknown liquid you used. You have been assigned the unknown number 29. Enter the unknown number for the unknown liquid: You have NOT entered the unknown number that you were assigned. Go back and enter the unknown number that you were assigned. From the procedure 2. Determine the mass of a dry 100 mL beaker to 0.001 g and record this mass. 3. Use a volumetric pipet to transfer 10.00 mL of one of the unknown liquids to the beaker. Follow appropriate pipetting technique for this transfer. 4. Determine the mass of the beaker and the unknown liquid to 0.001 g and record this mass. 5. Pour out the unknown into the waste beaker at your station. Clean the beaker and repeat the procedure twice, for a total of three trials. Trial 1: Mass of empty beaker (g) 69.928 Trial 2: Mass of empty beaker (g) +O/T. The volumetric pipet is labeled is 10.00 +0.02 mL. Trial 1: Unknown volume (ml) Trial 1: Mass of beaker + liquid (g) 77.739 +O/T REPORT SUMMARY
69.923 Ⓒ-0/T The volumetric pipet is labeled is 10.00 +0.02 mL. Trial 2: Unknown volume (ml) Trial 2: Mass of beaker + liquid (g) Trial 3: Mass of empty beaker (g) 77.789 ©G/T 69.924, 6/T- The volumetric pipet is labeled is 10.00 ± 0.02 ml. Trial 3: Unknown volume (mL) Trial 3: Mass of beaker + liquid (g)
77.814, O +0/T+ Part II - Density of a Regularly-Shaped Solid PREVIOUS ENTRY From the procedure 1. Your instructor will give you a solid object (cube or rectangular prism). Record the ID of the solid. You have been assigned the unknown number 57. Enter the unknown number for the regularly-shaped solid:
