How Many Atoms Thick Is A Sheet Of Aluminum Foil

Right now we are learning about moles and conversion factors.

How many atoms thick is a sheet of aluminum foil. Think of the foil as a bunch of spherical atoms stacked on top of each other and touching only at a tangent point. Finding a stock aluminum foil much thicker than this is often hard to find and requires a custom order. Please help how to calculate how many atoms thick is a sheet of aluminum foil. The thickness of aluminum foil is about 0 002 cm.

Counting atoms in a sheet of aluminum foil. According to the alcoa website aluminum foil is a flat rolled product rectangular in cross section of thickness from 0 006 quot 0 15mm to. 0 23 g divided by 2 70 g cm 3 0 2327 cm 3. How many al atoms thick is the aluminum foil if it is 0 00157cm thick.

1 al atom 286pm convert pm to m 286pm 2 86 10 10m convert m to cm 2 86 10 10m 2 9 10 8cm divide aluminum thickness and al atom thickness 1 57 10 3 chemistry. Record the title purpose materials a prediction for how many atoms thick a sheet of foil is procedure and result in a sheet of paper. Aluminum foil has a thickness of eq 2 86 times 10 3 eq cm. Most aluminum foil labeled extra heavy duty is between 0011 thick and 0016 thick.

I have to figure this out for chemistry and we took all the measurements in class the density of alumnium foil. A sheet of aluminum foil has a total area of 1 000 ft squared and a mass of 3 636 grams. How many atoms are there in a piece of aluminum foil 3 6 inches in length and 12 0 inches in width and 0 081 mm thick. How to measure the easiest way to measure the thickness of the aluminum foil is with a micrometer.

Okay so i m doing a chemistry lab where we were given a sheet of aluminum foil and have to calculate how many atoms thick the sheet is. This is a fairly rough estimate from classroom data. 0 8 cm times 0 7 cm times x 0 2327 cm 3. My teacher said conversion factors were key to answering the lab.

Assuming the aluminum atoms stack directly on top of each other use the diameter of an atom to figure out how many. A mole of aluminum weighs 27 grams the density of aluminum is 2 7 grams per cubic cm so one mole occupies a cube with volume of 10 cc. We took squares of aluminum foil measured the surface area and mass. Length of square cm area of square cm2 mass of al square g volume of al piece cm3 thickness of foil cm and the number of atoms in the.

How many atoms thick is aluminum foil. Or 1 cc contains 0 1 mols or 6 02e22 atoms. The cube root gives 3 92e7 atoms cm on a side multiply this by the thickness of the foil gives 75 000 atoms thick. How many atoms thick is a sheet of aluminum foil.

By dividing the mass by a known density value we obtained the volume of aluminum foil in our sample.
