Answer:
To understand why option 'C' is the correct answer, let's analyze the factors that determine the number of molecules in a gas sample.
1. Avogadro's Law:
According to Avogadro's law, equal volumes of gases at the same temperature and pressure contain an equal number of molecules. This means that if the temperature and pressure are the same for all three flasks, then they will contain an equal number of molecules.
2. Moles:
Moles represent the amount of substance present. If the moles of all the gases in the flasks are the same, then the number of molecules will also be the same. This is because the number of molecules is directly proportional to the number of moles.
3. Mass:
The mass of a gas sample depends on its molar mass and the number of moles. If the masses of the gases in the flasks are the same, it does not necessarily mean that the number of molecules will be the same. For example, CH4 has a lower molar mass compared to CO2 and Cl2, so to have the same mass, the number of molecules of CH4 would be higher.
Conclusion:
Based on the above analysis, we can conclude that option 'C' is the correct answer. In order for the three flasks to contain an equal number of molecules, the temperature and pressure of all the flasks should be the same. This is because Avogadro's law states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules. The masses of the gases and the moles of the gases do not need to be the same for the number of molecules to be equal.
