Chemists generally use the term atomic weight rather than average atomic mass. We state in the text that the latter term is more correct. By considering the units of weight and mass, can you explain why this is so? The response has to be a narrative, in the form of a paragraph showing work (mathematics) wherever applicable. This paragraph should be at least 10 complete sentences. These sentences must be explaining your answer.   please type the answer
