Question:

I was wondering if someone can answer this, and sort of explain it?

The aluminum in a package containing 75 ft^2 of kitchen foil weighs approximately 12 ouncesAluminum has a density of 2.70g/cm^3What is the thickness of the aluminum foil in millimeters and kilometers?

Answer:

Chickpea curry with riceCHickpeas- drain and rinseCurry powder or paste- heat with oil in a panBoil water, add rice, cook 20 minutes on simmerAdd the chickpeas to the curry pan, heat throughAdd anything you like- tofu, green peas, carrots, to the curry panBingo.
Quinoa with some nuts or rasines and some veggies that would be smashing
baked beans on toast, simple, quick and packed with iron
A yummy pasta sauce; handful of spinach, handful of basil, some nuts of your choiceAdd a little olive oil, bit of red onion, blitz it all in the liquidizer/food processorThen gently heat to put over pasta, or alternatively it's also fab in a potato bake; partially boil potatoes, add sauce, bake in the oven to finnish offI am quite addicted to this, and often fry off some tofu cubes to go in with it1 Or you can try dicing and par cooking all your favorite vegetables (Aubergines, mushrooms, courgettes work well!) and adding it to rice, then pop it in a frying pan with a little oil, and crumble in some tofu; it gives the feel of egg fried rice as the tofu cooks off, and is truly yummy!
This is the old thickness of Al foil problemI give this to my chemistry students the first week of schoolClearly, density is the ratio of mass to volume D m / V If you know the density of aluminum and the mass of the aluminum, then you can compute the volume V m / D You know that volume length x width x height (thickness) V L x W x H A L x W V A x H If you know the area of the aluminum foil, then you known the product of the length times the widthAll that is left is to compute the thickness75 (sq ft) 69,677.28 cm^2 (from Google) 12 ounces 340.194277 grams (from Google) H V / A and V m / D where H is the thickness H m / D / A or H m / (DA) H 320.2 g / (2.70 g/cm^3 x 69,677.28 cm^2) H 0.0017 cm or 0.017 mm since 10 mm 1 cm It would be totally impractical to express this in kilometers, and so I won't even dignify this part of the question with a response, but feel free to Google it yourself.
