Question : Which law was proposed in 1811, predicted that the same volume of gases at the same temperature and pressure would have the same number of molecules?
Option 1: Dalton’s law
Option 2: Gay-Lussac’s law
Option 3: Avogadro’s law
Option 4: Charles' law
Correct Answer: Avogadro’s law
Solution : The correct answer is Avogadro's law .
Avogadro's law, named after the Italian scientist Amedeo Carlo Avogadro, states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
