I read today that the FAA has extended the timeline in which it will be inspecting all charter operations specifications section A008 for compliance with operational control requirements.
We have three sizes of volumetric flasks to choose from: 100, 250 and 500 milliliters and they feature a single etched line or graduation to denote the fill-to-line at the chosen volume. Each size flask is specifically made for preparing solutions that correspond to its nominal value. For example, a 250 ml volumetric flask is the appropriate choice only when preparing a solution with a total volume of 250 ml.
You will then. add water to the flask from a filled 5-mL pipet, and then measure the mass of the flask and water. You will repeat this process three more times. After calculating the mass of the water that was. delivered each time from the pipet, you will calculate the volume of each addition from the mass.
