Stoichiometry/Moles
Flinn’s Exploring Chemistry™ Molar Relationships
and Stoichiometry Package See page 254.
Mole Set
Avogadro’s mole number, 6.02 x 1023, is huge!
Help clarify the concept of the mole by showing
your students 6.02 x 1023 atoms of four different
elements. Students will quickly grasp the ideas
of mass, moles and molar mass when they
compare these four specimens side by side.
Element specimens are copper, iron, zinc and aluminum.

Chemical Demonstration Kits—
Thermodynamics
Stoichiometry and Solubility—Mole Ratios
and Chemical Formulas
By: The Flinn Staff
Mix two solutions in various proportions
and measure the volume of precipitate
that forms in each mixture. Why do different
ratios of liquids produce different
amounts of precipitate? Which ratio will
give the most precipitate?
Concepts: Stoichiometry, mole ratio, double replacement reaction, solubility rules.
