Chapter 7, Problem 7P

On a periodic chart of the elements, molar mass (M), also called atomic weight, is often listed as though it were a dimensionless quantity (Fig. P7-8). In reality, atomic weight is the mass of 1 mol of the element. For example, the atomic weight of nitrogen $M_{nitrogan}=14.0067$ . We interpret this as 14.0067 g mol of elemental nitrogen, or in the English system. 14.0067 lbm/lbmol of elemental nitrogen What are the primary dimensions of atomic weight?
