Chapter 3 Stoichiometry 3-1Chapter As you have learned in previous chapters, much of chemistry involves using macroscopic measurements to deduce what happens between atoms and molecules. We will now explore the chemical counting unit that links the atomic and macroscopic scales, the mole. The mole...

solid, liquid, and gas all matter is made up of tiny particles called atoms and molecules that attract each other and move constantly a solid has a definite volume but not a definite shape a liquid has a definite volume but not a definite shape a gas does not have a definite shape and...
THE chapters which have been retained in this abbreviation deal with atomic and molecular theories, atomic and molecular weights, valency and chemical constitution, classification of the elements, the modern view of the atom and the molecule, and finally the colloidal state. The chapters omitted ...
