Station 1

Measure the mass of zinc contained in your sample. Use dimensional analysis to calculate the number of atoms in this sample.

Station 2

Measure the mass iron and copper in each sample provided. Calculate the number of moles for each and determine which sample contains more moles.

Station 3

Cut a perfect 15 cm x 15 cm square of heavy duty and regular aluminum foil. Measure the mass of each piece of aluminum. Calculate the number of atoms contained in each to determine if heavy duty aluminum foil really contains more aluminum than regular aluminum foil.
