At same temperature and pressure, equal volumes of gases contain the same number of:

• A. molecules
• B. electrons
• C. protons
• D. particles

Avogadro's hypothesis: All gases containing equal moles if substance occupy the same volume at the same temperature and pressure.

Hence, equal volumes of gases will have an equal number of particles that can be atoms or molecules.
