Stoichiometry: Molecular Mass (3 of 4)

previous page Previous page    Next page next page

Yet another term for gram formula and molar mass is Molecular Mass. Again, look on the periodic table, find the gram atomic mass of each atom, and add them together. For example, for PCl3 you need to add the mass of on P and three Cl's together.

So far we have three terms to describe the mass of one mole of a molecule:
  • Gram Forumla Mass (GFM)
  • Molar Mass
  • Molecular Mass

One more after this and then you've got the major terms.
