Unformatted text preview: 4. Weigh a clean dry 50 mL Erlenmeyer flask on the balance. Fill a beaker with distilled water and measure the temperature of the water with the thermometer. Using a 10 mL pipet, take 10 mL of water from the beaker and add it to the flask. Reweigh the flask. Using the difference in the two masses calculate the mass of the 10 mL. Using the density of the water from the table in the lab manual calculate the volume of the water. This is the calibrated volume of the flask 5. Weigh a clean dry 50 mL beaker. Add 10 mL of antifreeze to the beaker. Reweigh the flask. Calculate the mass of the 10 mL by using the difference in mass. Calculate the density using the equation D=m/V. Laboratory Cautions 1. Do not pipet by mouth. 2. Do not drop objects on pan of balance. 3. Do not weigh warm objects....
