The problem reads quot;a sheet of aluminum foil has a total area of 1.000 square ftand a mass of 3.937 gWhat is the thickness of the foil in millimeters? (Density of Al 2.699 g/cm3.)OK, density/mass volume; volume divided surface area thickness.2.699 / 3.937 06855 cubic cm x 10^3, equals 685.5 cubic mm1000 square feet 92903040 square mm so in total, it's 685.5cubic mm / 92903040 square cm 7.38 x 10 ^ -6.well according to my online homework, it's not.
You just got it upside downVolume mass/density g/ (g/cm3) cm3 density/mass (g/cm3)/g 1/cm3, which is reciprocal of volume3.937/2.699 1.4587 cc 1458.7mm3 1458.7/92903040 1.5701x 10 ^ -5.mm
This is most likely from the oxidation of the AluminumSomething like this2Al+3H2OAl2O3+3H2 But if you are getting nauseous, it is very likely your aluminum may be tainted by some other substancePlease, describe the smell?
To answer the part about what to do, I would first clean it wellYou can buy some aluminum polish in either hardware stores or automotive storesThat will probably help clean off the oxidationThen, take some rubbing alcohol and, while wearing gloves, clean off all the residue left by the polishYou wan the metal to be very cleanYou can then take a spray can of clear coat (found in most hardware store paint sections) and give it a light coating of clearThis will lock the aluminum in and keep it from reactingThis is what is done for most aluminum alloy wheelsJust make sure to make light coats so that the coverage is even.
