The atomic mass, in grams, is the mass of one mole of atoms.
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
One mole of atoms of an element is equal to the atomic mass of that element expressed in grams. Nitrogen-14 so one mole of nitrogen weighs 14 g
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
When isotopes are considered, they have the same atomic number but differed mass numbers.
The mole is the atomic weight expressed in grams.

The atomic mass, in grams, is the mass of one mole of atoms.
The mass of one mole of a substance, usually expressed in grams or kilograms.ORThe sum of the atomic weights of all the atoms in a molecule. Also called formula weight.

HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60

The atomic mass is grams/mole So when you have e.g. 12 grams of carbon which has atomic mass = 12, you have one mole. ( Avogadro's number is one mole: 6.02×10²³ )
Simple: the atomic weight expressed in grams. Example for dysprosium - 162,500 grams.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
