Question

10) 6 What can be deduced about two gases that have the same relative

molecular mass? A They have the same boiling point. B They have the same number of atoms in one molecule.

C They have the same rate of diffusion at room temperature and pressure. D They have the same solubility in water at room temperature.

Answer 1

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
