1.a. Determine the thickness of each piece of aluminum foil in micrometers by using the density of aluminum.
Density of Aluminum: 2.70 g/cm3
| Al foil piece 1 | Al foil piece 2 | Al foil piece 3 | |
|---|---|---|---|
| Length (cm) | 10.30 | 10.30 | 10.15 |
| Width (cm) | 7.20 | 7.95 | 7.65 |
| Mass (g) | 0.35 | 0.34 | 0.39 |
| Thickness (μm) |
1.b. Calculate the average of three measurements and the average absolute deviation.
Average thickness (μm): ?
2.b. Calculate the average of three measurements and the average absolute deviation.
Average density (g/mL): ?
2.c. Using the reference table below, find the density of water and then use it as the reference value to calculate the percent error of your averaged measured value for the density of water from 2.b.
Use the table of water density at different temperatures to find the denisty of water at 18.0 °C. Include all seven decimal places provided in the table. Use this density as the reference value for the density of water in your percent error calculations.
2.d. Percent error, reported to one decimal place: ?
