1. Thickness of a Thin Layer
Problem: What is the thickness of regular and heavy duty aluminum foil?
Group Data:
Calculations: (all numbers have units)
Class Data:
Conclusion: If one atom of Aluminum is 2.9 x 10-8 cm thick,
How many atoms thick is regular foil?
How many atoms thick is heavy duty?

2. Thickness of a Thin Layer
What is the formula for volume of a rectangular solid? What is the unit for volume?
What is length x width commonly known as? What is the unit?
Solve for h ( rearrange the equation to read h= ? )
The density for Aluminum in 2.7g/cm3.
If the mass of a piece of Aluminum foil is 3.14g
what is the volume? (use DA and show all units)
Design a data table to help you find h for both the regular and thick foil.
