Why does one mole of a gas occupy 22.4 L, no matter what the gas happens to be?
A) Because gas laws are all the same.
B) Because gas particles actually occupy very little of that volume.
C) Because all gas particles in any gas are of high enough energy.
D) None of the above; rather, there are different volumes for different gases.
Mole
A mole is a unit of measurement used in chemistry to quantify the amount of substance, equivalent to approximately 6.022 x 10^23 particles, atoms, molecules, ions, or electrons.
Gas
One of the four fundamental states of matter with indefinite shape and volume, composed of molecules in constant random motion.
- Determine the volume occupied by one mole of a gas under standard temperature and pressure conditions.

Final Answer :
B
Explanation :
The volume of 22.4 L for one mole of any gas at standard temperature and pressure (STP) is largely due to the fact that the particles themselves occupy a very small portion of the volume, with the majority being empty space. The behavior of ideal gases, according to the Ideal Gas Law, supports this observation, assuming negligible volume of the gas particles themselves and no intermolecular forces.
