Equal moles of all gasses 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 22.4dm³ Moles equal means volume equal ● Mole= Mass/ Mr Mass = Mole x Mr All gases would have different Molecular mases 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.
