Expert Answer
Atomic mass of an element is defined as the number of times an atom of that element is heavier than 1/12 of the mass of carbon atom. Units of atomic mass are grams or a.m.u.
Molar mass is the mass of one mole of an element and its units are g/mol or Kg/ mol.
Molar mass is equql to atomic mass expressed in grams.
For example molar mas of sodium atoms is the mass of 1 mol of sodium atoms and it is 23g/mol and it has 6.023×1023atoms.
yes the magnitudes of both the atomic mass and molar mass is same fo an element.
i mole of atoms= 6.023×1023= Atomic mass of an element expresed in grams.
