Mole In The Bag

How Big Is A Mole? Why does a mole of copper weigh more than a mole of sulfur?

Students will answer these inquiry questions and more while introducing the concept of the mole and its importance in chemistry with this visual demonstration. The bags contain several elements and compounds and are available for students to examine, weigh, and explore. Use the mini bags to demonstration fractions of a mole, then bring the bags out again to demonstrate the relationship between moles and molar solutions. This is a great teaching aid for introducing moles, Avogadro's Number, gram molecular weight, and morality.
