How Many Atoms Thick Is A Sheet Of Aluminum Foil

Finding a stock aluminum foil much thicker than this is often hard to find and requires a custom order.

How many atoms thick is a sheet of aluminum foil.

My teacher said conversion factors were key to answering the lab. How to measure the easiest way to measure the thickness of the aluminum foil is with a micrometer. The cube root gives 3 92e7 atoms cm on a side multiply this by the thickness of the foil gives 75 000 atoms thick. Please help how to calculate how many atoms thick is a sheet of aluminum foil.

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. Right now we are learning about moles and conversion factors. By dividing the mass by a known density value we obtained the volume of aluminum foil in our sample. 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.

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. 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. A sheet of aluminum foil has a total area of 1 000 ft squared and a mass of 3 636 grams. 0 8 cm times 0 7 cm times x 0 2327 cm 3.

Aluminum foil has a thickness of eq 2 86 times 10 3 eq cm. Assuming the aluminum atoms stack directly on top of each other use the diameter of an atom to figure out how many. X 0 415536 cm. Counting atoms in a sheet of aluminum foil.

How many atoms thick is aluminum foil. I have to figure this out for chemistry and we took all the measurements in class the density of alumnium foil. Construct a data table with the headings listed below. Or 1 cc contains 0 1 mols or 6 02e22 atoms.

Most aluminum foil labeled extra heavy duty is between 0011 thick and 0016 thick. 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. Biche answer approximately 193 000 atoms thick. Think of the foil as a bunch of spherical atoms stacked on top of each other and touching only at a tangent point.

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. 0 23 g divided by 2 70 g cm 3 0 2327 cm 3. We took squares of aluminum foil measured the surface area and mass. How many atoms thick is a sheet of aluminum foil.

How many al atoms thick is the aluminum foil if it is 0 00157cm thick.
