Three identical flasks contain three different gases at standard temperature and pressure. Flask A contains C₂H₄ flask B contains O₃, and flask C contains F₂. Which flask contains the largest number of molecules?

Question

Quizplus · Accepted Answer

The three flasks contain different gases, but all at standard temperature (0°C) and pressure (1 atm). The number of molecules in a gas is directly proportional to its moles, which is in turn proportional to its volume when compared at the same temperature and pressure. The volume of each flask is not given, so we cannot determine which flask contains the largest number of molecules. However, because the conditions are the same for all three flasks, we can conclude that they contain the same number of molecules. Therefore, the answer is D, all contain the same number of molecules.
