Why can't you express the mass of atoms in units of grams?

This is about the Relative Atomic Mass, but I can't find the answer!

    You can. That's exactly what a mole is.

    A mole is the number 6.02 x 10^23 which is how many atoms of that substance you need to convert the relative atomic mass on the periodic table to grams which is useful for the real world.

    Relative atomic mass is important for the theoretical and grams is useful for the practical the mole is what converts one to the other.

    EG: 1 mole of Hydrogen weighs 1 gram.

    1 mole of Helium weighs 4 grams.

    1 mole of Carbon weighs 12 grams

    etc.

    Hope this helps.
