  15. 10.1 The Mass of a Mole of an Element • The atomic mass of an element expressed in grams is the mass of a mole of the element. • The mass of a mole of an element is its molar mass.

  16. 10.1 The Mass of a Mole of a Compound • Substitute the unit grams for atomic mass units. Thus 1 mol of SO3 has a mass of 80.1 g.
