Question

Do equal volumes of the same gas at the same temperature and pressure contain equal numbers of molecules (number of moles)?

Answer 1

Answer:Therefore, there must be a direct relationship between these volumes of gases and the number of molecules they contain. Avogadro's law says that: Equal volumes of different gaseous substances, measured under the same pressure and temperature conditions, contain the same number of molecules.
