Is Atomic Mass and Atomic Weight the same terms? Or is Atomic mass and Mass Number the same terms? On the MCAT Kaplan books it says that atomic mass and mass number are the same thing but online and other chemistry textbooks, atomic mass and atomic weight are the same thing. Can someone please clarify which two terms are the same thing or are they all different? I really need help to make sure I understand this for the MCAT.
