Detailed Solution

●        We are aware that aluminium has an atomic number of 13. Consequently, an aluminium atom has 13 electrons orbiting its nucleus.
●        The atom remains electrically neutral because the amount of electrons and protons is constantly equal. Consequently, an aluminium atom's nucleus contains 13 protons.
●        The aluminium atom's nucleus contains fourteen neutrons.
●        Any element's atomic mass is calculated by adding its neutron count to its atomic number.
●        Aluminum's atomic number times its mass plus The aluminium atom's neutron count
●        Change the atomic number to 13 and the number of neutrons to 14. Consequently, Aluminium Mass = 13 + 14 = 27 u.
●        Aluminium therefore has a mass of 27 u.
