Question

Which of the following statements represents Avogadro’s hypothesis?

• A. Atoms of different elements may combine with each other in a fixed, simple, whole number ratio to form compounds
• B. Equal volumes of all gases under the same temperature and pressure conditions contain an equal number of atoms
• C. Equal volumes of all gases under the same conditions of temperature and pressure contain an equal number of particles
• D. Gases react together in volumes which bear a simple ratio to one another

Answer 1

The correct option is C Equal volumes of all gases under the same conditions of temperature and pressure contain an equal number of particles

Avogadro’s law states that equal volumes of all gases under the same temperature and pressure conditions contain an equal number of molecules.
