Aluminium turnings. This pile of aluminium weighs 27 grams and represents one mole of the element. The atomic weight of aluminium is 27. A mass in grams of an element equivalent to its atomic weight always contains the same number of atoms, regardless of the element. This is called a mole. Aluminium is a very light, malleable metal. Its alloys are used in the construction industry.
