Mole Samples and Molar Mass


Publication 10634

Price: FREE

Why do different elements have different molar masses? What is the molar mass of a compound? Use this two-part activity to introduce students to the concept of molar mass and then evaluate their ability to carry out mole and molar mass calculations. After viewing a variety of mole element samples on display in Part A, students are assigned a “mole baggie” in Part B. These mole sample bags contain pre-measured amounts of white mystery compounds. Students must calculate the molar mass of the compound in the bag and determine its identity from a list of possibilities.
