Aluminum Foil Lab

Procedure:

1. First, my lab partner, Zoe, and I weighed our piece of aluminum foil by placing it on a scale. We recorded all the digits of this measurement.
2. Next, we found the volume of the piece by using the density of aluminum with the density equation: density = mass/volume.
3. Using a ruler, we measured the length and width of the piece of foil (as shown below).
4. Finally, we calculated the height of the aluminum foil using the equation for volume: volume = length x width x height. Our last step was converting our calculated thickness into millimeters.

Calculations (a deeper look):

density of aluminum (ours) = 2.8 g/cm^3

mass of aluminum foil = 0.43 g

To find the volume of the aluminum foil, we divided the mass by the density.

volume = mass/density = 0.43/2.8 = 0.15 cm^3

length of aluminum foil = 11.52 cm
width of aluminum foil = 9.21 cm

To find the height, or thickness of the aluminum foil, we divided the volume by the product of the length and width.

height = volume/(length x width) = 0.15/(11.52 x 9.21) = .0014 cm

.0014 cm = .014 mm

Thickness of aluminum foil = 0.014 mm
