8. Draw and label a diagram to help you solve the following problem. You have an empty beaker. The mass of the empty beaker is 68.1245 g. You use a 25 mL volumetric pipette and transfer 25 mL of deionized water to the beaker. The mass of the beaker containing water is 93.0329 g. The temperature of the laboratory is 18.1°C. Use the appropriate mass-to-volume conversion factor for water and calculate the actual volume delivered from the 25 mL pipette.
