GENERAL CHEMISTRY 101
CALCULATIONS with CHEMICAL
FORMULAS and EQUATIONS
In this and subsequent sections, we shall use what we have learned about chemical structure, electron configuration, and chemical formulas to study the mass relationships of atoms and molecules. [..see syllabus...] (Its important that you complete the "self- .......exercises in each section!) By international agreement, an atom of the carbon 12 isotope(12C) has a mass of exactly 12 atomic mass units(amu). Therefore, 1 amu is one-twelfth of the mass of one carbon atom. The unit defined by the SI system is the mole(mol), which is the amount of substance that contains as many elementrary entities as there are atoms in exactly 12 g of the carbon-12 isotope. Experimentally the number is •Stoichiometry(complete unit) Introduction/Mole problems •1 mol = 6.0221367 x 1023 particles(atoms) Patterns of chemical Reactivity Stoichiometry: Chemical Formulas and Composition Stoichiometry: Chemical Formulas and Equations Empirical Formulas from Analyses Chemical Change Balanced Equations Limiting Reactants •Stoichiometry[THE CHEMISTRY COACH SITE](Tutorials)

Concurrently you should review the appropriate 
rea(s)
as needed.
In addition to the regular homework assignments of problems from the text,
self paced exercises, activities, quizzes, and virtual/practicals are
incorporated in each major section of this course. It is important, to
the extent possible, that each student take maximum advantage of these
study aids!
