Example Exercise 9.1 Atomic Mass and Avogadro’s Number

Molar Mass Calculations. We begin by finding the atomic mass of each element in the periodic table. The molar mass equals the sum of the atomic masses expressed in g/mol. (a) The atomic mass of Ag is 107.87 amu, and the molar mass of silver equals 107.87 g/mol. (b) The sum of the atomic masses for NH. 3 is 14.01 amu + 3(1.01)amu = 17.04 amu ...
