What’s another name for a mole? Why it’s Avogadro’s number, (6.02 x 1023), a basic unit of measurement of molecules and atoms in chemistry. Celebrate Mole Day on October 23, from 6:02am to 6:02pm using the following resources:
Follow the evolution of the definition of a mole in Chemistry: Challenges and Solutions, unit 6, “Quantifying Chemical Reactions.”
See what Amedeo Avogadro (year 1811) looked like, his influences, and his impact on those who came after him in the Chemistry Timeline for Chemistry: Challenges and Solutions.
Use an activity that combines a familiar game with chemical calculations to help students visualize what a mole is in Reactions in Chemistry, workshop 1, “Atoms and Molecules.”
Your students can learn about isotopes, moles, and calculating atomic mass using The Periodic Table Interactive.
The Mechanical Universe…and Beyond, program 49, “The Atom,” discusses Avogadro’s number and its role in the development of atomic theory.
