All elements have an (atomic) weight or mass.
Vanadium is the element that has an atomic weight of 50.942.
Petroleum is not an element and therefore has no atomic weight!

a fly is not an element so it does not have an "atomic" weight. It does have a mass or weight however
Selenium (Se) has an atomic weight of 79,04.
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
Its not an element....
