Learners examine how chemists use moles to "count" atoms by weight. Examples are given.
By Debbie McClinton Dr. Miriam Douglass Dr. Martin McClinton
Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
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.
