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.
81. A flask with a volume of 1.50 L, provided with a stopcock, contains ethane gas (C 2 H 6) at 300 K and atmospheric pressure (1.013 Ã 10 5 Pa). The molar mass of ethane is 30.0 g/mol. The system is warmed to a temperature of 380 K, with the stopcock open to the atmosphere.5. Calculate the volume of 1.00 mol of liquid water at a temperature of 20 Â°C (at which its density is 998 kg/m 3 and compare this volume with the volume occupied by 1.00 mol of water at the critical point, which is 56 Ã 10 â6 m 3. Water has a molar mass of 18.0 g/mol.
