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.
The Three States of Matter
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated and interactive object, learners examine the properties of liquids, solids, and gases.
Calculation of Atomic Weight from Isotopic Composition
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the method for calculating the atomic weight of copper from the natural percent composition of each of its two isotopes.
Absolute Zero Temperature
Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.
By Jill Larson
In this interactive object, students examine how the volume and temperature of an ideal gas relate under conditions of constant pressure and quantity.
Weight- Volume Relationships: Dry Density
By Steve Whitmoyer
Students read how to determine and calculate the dry density for a given sample of soil or aggregate based on the mass-volume relationship.
Weight- Volume Relationships: Saturated Density (Metric)
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
Determining Empirical and Molecular Formulas
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.
Newton's Second Law of Motion
