It is the fact that 22.414 dm3 of any gas has a different mass but the same number of:
Correct answer: B. Particles
- A. Atoms
- B. Particles
- C. Molecules
- D. None of these
Explanation
22.414 dm3 of each gas has a different mass however the very same number of particles. The reason is that the masses and the sizes of the monoatomic or diatomic gases don't affect the volumes.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
