Which law states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules?

Which law states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules? Correct Answer Avogadro’s law

  • Boyle’s law states that “At constant temperature, the volume of a given mass of a dry gas is inversely proportional to its pressure.”
  • Avogadro’s law: This law states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules.
  • Gay Lussac’s law: This law states that at constant volume, the pressure of an ideal gas is directly proportional to its absolute temperature (in Kelvin).
  • Charles’ law: This law states that the volume of gas equals a constant value multiplied by its temperature as measured on the Kelvin scale.
