Mole Mountain Conversions Activity
Purpose: The purpose of this activity is:
1) to determine the amount of moles, and particles in a measured sample of a substance, and
2) to determine the identity of an element by determining its molar mass
Materials: Balance, Mole Mountain, periodic table, calculator, pencil
Procedure:
Part One: Go around to each station and fill in the following table.
Data:
Sample Number |Sample |Mass of Container + Sample (g) |Mass of Empty Container (g) |Mass of Sample(g)
