**D. Using the Balance to Calibrate Your 10 mL Pipet** - **Temperature of water used in pipet:** 22°C - **Corrected temperature:** (Blank) **Trial Measurements:** | | Trial 1 | Trial 2 | Trial 3 | |----------------|-------------|-------------|-------------| | Mass of Erlenmeyer plus ~10 mL H₂O (gross mass) | 35.87 g | 35.62 g | 36.00 g | | Mass of Erlenmeyer (tare mass) | 25.89 g | 25.76 g | 26.04 g | | Mass of ~10 mL of H₂O (net mass) | 9.98 g | 9.86 g | 9.96 g | **Note:** The net mass of ~10 mL of H₂O is calculated by subtracting the tare mass of the Erlenmeyer from the gross mass. *Copyright © 2018 Pearson Education, Inc.* --- The table above shows the calibration data for a 10 mL pipet using an Erlenmeyer flask. The trials have been repeated three times to ensure accuracy and consistency. The temperature of the water is initially recorded, but any correction needed for temperature is not provided.
