According to Avogadro's law, 0.899g of 1dm3 H2 and 1.4384g of 1dm3 O2 have _number of molecules.
Correct answer: A. Same
- A. Same
- B. Different
- C. H2 has more
- D. O2 has more
Explanation
According to Avogadro's law, 0.899g of 1dm³ H₂ and 1.4384g of 1 dm³ of O₂ have the same number of molecules. Avogadro's law states that "equal volume of all gases beneath comparable situations of temperature and pressure have an equal number of molecules in it."

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.
