Question:

A semi involved chemistry conversion problem that I can't figure out?

The aliminum in a package containing 75ft^2 of kitchen foil weighs approximately 12 ouncesAluminum has a density of 2.70 g/cm^3What is the approximate thickness of the aluminum foil in millimetersIt also gives how much 1 ounce is in grams, (1oz 28.4 g)Ive gotten all sorts of anwsers but just don't know if any are correct.

Answer:

a 1 lb box of powdered sugar less 1/3 cup1 stick of butter or margarine and about 13 oz of crunchy p.bmix and roll into ballsi dip mine in chocolate but it isn't necessary
Don't need the width if you have the area 1 ft? 144 in? ( 2.54 cm/in)? 144(6.452) 929.0 cm?/ft? Total area 75 ft?(929 cm?/ft?) 69,677 cm? Density mass/volume 2.70 g/cm? 12 oz(28.4 g/oz)/ Volume 340.8 g/ Volume Volume 340.8g / 2.70 g/cm? 126.2 cm? To get the thickness divide volume by area Thickness 126.2 cm?/69677 cm? 0.00181 cm 0.018 mm So in one equation: Thickness Volume/Area Thickness (mm) (mass/density)/(Area) (10 mm/cm)((12 oz)(28.4 g/oz)/(2.70 g/cm?)) ????/((75 ft?)(144 in?/ft?)( 2.54 cm/in)?) (10 mm/cm)(126.2 cm?))/69677 cm? 0.018 Best to you
BEST PEANUT BUTTER BALLS 1 cup light corn syrup 1 cup sugar 1 cup peanut butter 6 cups corn flakes Bring corn syrup and sugar to a boil, stirring constantlyBoil for ONLY 3 minutes (any longer the balls will be hard)Remove from heatStir in peanut butterPour over corn flakes and mixWait a few minutes, then roll into balls.
