Learners examine how chemists use moles to "count" atoms by weight. Examples are given.
By Debbie McClinton Dr. Miriam Douglass Dr. Martin McClinton
Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.
By Roger Brown
Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.
