Question

Which of the following 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 molecules.
• 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 molecules.

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