Question:

10 points! Chemistry math problem?

A sheet of aluminum foil has an area of 1.000 ft^2 and a mass of 3.616gwhat is the thickness of the aluminum foil in millimeters? (density of Al equals 2.699 g/cm^3)I would really appreciate the help

Answer:

The foil is simply a very thin rectangular objectThis problem is more about unit conversions than anything elseTo get the volume, divide the mass of the aluminum by the density, that gives you a volume with units of cm3The volume of the foil is its area thicknessConvert 1 ft2 to cm2Calculate the thickness in cm, convert the thickness to mmI get 0.0144 mm
