Chapter 3. Stoichiometry: Mole-Mass Relationships in ...

• For compounds, the molecular mass (in amu) is numerically the same as the mass of one mole of the compound in grams. • Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. • Molecular mass H 2 O = (2 x atomic mass of H) + atomic mass of O = 2(1.008 amu) + 16.00 amu = 18.02 amu
