HOW TO FIND THE THICKNESS OF ALUMINUM FOIL
Remember the formula,
density = mass/volume
Also remember the formula, volume = length x width x height. Thickness will substitute height, therefore making the formula, volume = length x width x thickness. Since length x width = area, we could rewrite the density formula to:
density of Al = mass of Al / area of Al x thickness of Al
The formula can be rearranged into:
thickness of Al = mass of Al / area of Al x density of Al
Information needed:
- length and width of aluminum square
- mass measured by a centigram measure
Exponential Error
It expresses the future growth a very small error can become.
Formula:
Exponential error = your measurement - Accepted value / Accepted value x 100 --> %
*It is written as a %
Accepted Value
A value of a substance accepted and approved by many
*given by instructor
