How does Avogadro's number relate to the atomic mass and moles of an element? Avogadro's number can be used to convert the atomic mass of an element to the mass of one mole of that element The mass of one mole of an element can be used to convert the atomic mass of that element to Avogadro's number. Avogadro's number is not related to the atomic mass of an element or the mass of a mole of that element. The...

Part A What statement best describes the atomic weight of an element? View Available Hint(s) What statement best describes the atomic weight of an element? Atomic weight is the sum of the masses of the isotopes. Atomic weight is the product of the relative abundances masses. Atomic weight is the sum of the masses of the isotopes multiplied by their relative abundances. Atomic weight is the masses of the isotopes less their relative abundances.
