For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
The formula of aluminium chloride is AlCl3. The atomic  weight of aluminium is 27 and that of chlorine is 35.5. That means  35.5*3 grams of chlorine will combine with 27 graâ¦ms of aluminium.  So 33 grams of chlorine will combine with 8.37 grams of aluminium.  The addition of both makes it 41.37 grams.
