If the number of molecules of different gases are the same at S.T.P., the occupied volume will be _:
Correct answer: B. Same
- A. Greater
- B. Same
- C. Smaller
- D. Twice
Explanation
At standard temperature and pressure, 1 mole of gas has a volume of 22.4 dm3. This means that every gas occupies the same volume provided that the number of moles is the same.

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.
