Which law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules?
Correct answer: D. Avogadro's law
- A. Boyle's law
- B. Charles' law
- C. Gay-Lussac's law
- D. Avogadro's law
Explanation
Avogadro’s law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. This is why gas volume can be related directly to the amount of gas under fixed conditions.
