Question:

A sheet of aluminum foil that is 11 inwide and 12 inlong weighs 8.90 grams.?

If aluminum has a density of 2.70 g/cm^3, what is the thickness, in millimeters, of the foil? (Assume the foil is pure aluminum)Report answer to correct number of significant figures(1 in 2.54 cm)

Answer:

properly!!! a million inch 2.fifty 4 cm hence, quantity abc2.fifty 4^3 cm^3 Density Mass/quantity quantity Mass/Density 8.9/2.7 3.296 m^3 quantity (1112C)2.fifty 4^3 3.296 hence, C 0.0015 in hence, the thickness of the foil is 0.0015 in
