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.
A sample of gas (1.9 mol) is in a flask at 21 Â°C and 697 torr. The flask is opened and more gas is added to the flask. The new pressure is 795 torr and the temperature is now 26 Â°C. There are now _____ mol of gas in the flask.
