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.
These isotopes with an additional neutron add a tiny amount to hydrogens average atomic weight.The atomic weight of hydrogen is 1.0079, which means that one mole of hydrogen atoms (or 6.0221 x 1023 atoms of hydrogen) has a mass of 1.0079 grams.
