One should use an appropriate Periodic Table or look up in wikipedia by typing the elements name correctly and scroll down the collumn at the right (looking for 'standard atomic weight' or just 'atomic weight').
This is not exactly the same as the mass number.
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

The atomic mass of every element is given in the box for that element in the periodic table of elements.

Atomic Mass of element - the number the protons.

The number of neutrons= Atomic mass of an isotope-Atomic number of the elemnent For the atomic weights of elements (not mass) please read the IUPAC report at the link below.
