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.
Determining Empirical and Molecular Formulas
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
By Terry Bartelt
Learners view an animated presentation showing how the pH level of a cleaning solution is controlled in a closed-loop system in a manufacturing setting. A quiz completes the activity.
Naming Binary Ionic Compounds Containing Fixed Oxidation State Cations
Learners examine a table containing the names of common cations and anions. They then check their knowledge by answering a series of questions.
