Mole Mountain Conversions Activity - Weebly



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)

(subtract previous 2 columns) |Molar Mass of Sample (g/mol) |Moles of Sample (mol) |Number of Particles.

(With unit) | |1 |Tin Metal (Sn) |107.0 |94.3 | | | | | |2 |Potassium chloride (KCl) |8.6 |6.2 | | | | | |3 |Carbon (C) |159.1 |94.3 | | | | | |4 |Sodium bicarbonate (NaHCO3) |14.0 |6.2 | | | | | |5 |Iron (III) chloride hexahydrate (FeCl3 (6H2O) |186.7 |94.3 | | | | | |6 |Lead (Pb) |239.8 |94.3 | | | | | |7 |Copper (II) sulfate pentahydrate

(CuSO4 (5H2O) |223.2 |94.3 | | | | | |8 |Calcium carbonate

(CaCO3) |109.4 |94.3 | | | | | |9 | Sucrose

(C6H12O6) |8.8 |6.2 | | | | | |10 |Manganese dioxide
