Lab Experiment

Today during class we did Experiment 2E, "Determining Aluminum Foil Thickness".
We had 3 rectangular pieces of aluminum foil then measured each one using significant figures.
Next, we used a centigram balance to determine the mass of the piece of foil and recorded it on our table.

To find out the thickness of each piece of tin foil, we first had to figure out what the volume by using the equation : V=M/D
When we got the volume, we used the quation V=LWH to determine the thickness of te foil. We expressed our answer with scientific notation.
