Equal moles of all gases at STP have
Correct answer: B. Different masses but the same volume
- A. Same mass but different volumes
- B. Different masses but the same volume
- C. Same mass and same volume
- D. Different volume and different masses
Explanation
Volume = mole x 22.4dm³Moles equal means volume equalMole= Mass/ MrMass = Mole x MrAll gases would have different Mr so Masses are different.

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.
