Lab 2E occurred on November 3, 2010. In this class we used basic math formulas to calculate the thickness of aluminum foil pieces. These formulas are.
V=L*W*H, D=M/V, or V=M/D. Basically each group weighed each piece of aluminum foil. We were then given
the density of each piece, which is
2.70g/cm^3. Our next step was to measure the length and width of the aluminum with our ruler. After that we would find the volume by dividing the mass by the density. Once we got the voulme, we divided it by the length and width to get the
height (aka Thickness).
We also used a formula to calculate if there was any errors with our test results.
experimental error = estimated measurement - accepted value x 100%
accepted value
Well that wraps about everything up. This lab was fun and easy. It was fun because we didn't have to wear any goggles. LOL, jokes.
