Moles, percent composition, and the empirical formula

Description

When is a mole not a mole? Section one of this program demystifies concepts such as Avogadro's Constant, molecular mass, and molar mass. In section two, the Percent Composition Formula is spotlighted, while section three addresses the Empirical Formula and its use in determining formula weight. The calculation of mass in the conversion of magnesium to magnesium oxide in a segment called "Cooking with Professor Rowley" ties things together.
