What is the difference between atomic mass, atomic weight, and molar mass?

atomic mass: the sum of the number of protons and neutrons in an element
atomic weight: the weighted average of the masses of an element's naturally occurring isotopes
molar mass: the mass (in g) of one mole of an element or compound

atomic mass: the mass of a single atom of an element or isotope
atomic weight: the weighted average of the masses of an element's naturally occurring isotopes
molar mass: the mass (in g) of one mole of an element or compound
