How much does an aluminum Atom cost.The goal of this problem is to determine the cost of a single atom in a roll of aluminum foilMark has purchased a 200 sq.ftroll for $4.106.02 x (10 to the 23rd) atoms of aluminum have a mass of 26.98g.As a student int his lab, you will provided with only one sheet of aluminum : Length 5.7 cm Width 4cm Mass of sample sheet 0.080gFor each calculation there should be some accompanying verbal description of what that calculation is going to accomplishWhat does the result mean?What I did is: found the area of the sheet, then how many atoms are in the sheet, then I found how many atoms are in the 200sq.ft of aluminum by multyplying the area of the sheet by 0.0011Then I wanted to convert the area of the sheet, which is in sqcmto sq.ft but I got stock, I couldnt convert it.Then finally I ended up with this equation 200sq.ft x (1.78 x (10 to the 21st)) ÷ 0.025 ??
I think the brightly colored acrylic yarn is as scratchy as you can getAlternatively, you could get raw sheeps wool and throw sand into it, and then spin your own yarnbut i'm guessing that as you touched the raw sheeps wool, and got that lanolin on your hands, you'd want to just rub it all over yourself and hmm remind me about this on friday please.
Try a particularly rough rag woolI have a sweater made out of some stuff we bought in QuebecEvery time I wear it my neck breaks out in a rashIf you wish I will check to see if we have any left.
I'm going to need to see some video/pics of your problem, just to see exactly what we're dealing withOnly then will I be able to subscribe the right type of yarn.
Besides categorizing yarn left-overs in zip lock bags by color and type of yarn (you don't want to store wool with acrylics), and using the three ring binders with plastic sheet protectors for computer patterns or patterns I've cut out of magazines I no longer want, I also use some plastic holders to put my paperback books and leaflets in the bindersAnnie's Attic has some in their last catalogThey slip over the pages of your book to the center and have a three hole punch on them to hook them into the binderIf you use the view binders, you can make decorative binder spines and covers for your categories of patternsI also use the hard plastic magazine holders that you find in office supply stores and categorize patterns and pattern books by crochet, knit, cross-stitch, etcYou can also make these by taking a cereal box and cutting it on two sides diagonally and then covering with contact paper, fabric or whatever, but the hard plastic ones are cheap and come in lots of colorsIf floor space for shelves to store the magazine holders is a problem, put some shelves up higher, around each wall to store themIt really helps keep them organizedI have 60 gallon plastic tubs for skeins of yarn, but cubicles would be more ideal if you have the space in a closetAnother room or two for yarn, crafts and sewing would be ideal!! )
This is just a bit tricky because of how the question was stated but really easy when you understand the problem The first step is to get the number of atoms in 200 sq ft of aluminum foil: of atoms (200 sq ft) x (0.080g / 0.02454 sq ft) x (6.02 x 10^23 atoms / 26.98 g) about 1.45 x 10^25 atoms If you're wondering where I got 0.02454 sq ft, that's the area of the given sheet of aluminum foil (L 5.7cm, W4cm)I just converted to ftNow that you have the number of aluminum atoms in 200 sq ft of aluminum, you just have to divide the cost with that number: cost per atom of Al $4.10 / of atoms; substitute the above value and you will get roughly 2.8 x 10^(-25) dollar per atom Hope this helps.
