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.
The following procedure was used to determinethe volume of a flask. The flask was weighed dry and then filledwith water. If the masses of the emptyflask and filled flask were56.12g and 87.39 g. respectively, and the density of water is0.9976 g/cm3 calculate the volume of the flask incm3. i did like this. mass of empty flask : 56.12g.
