Gold, which has a density of 19.32 g/cm³, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber. (a) If a sample of gold with a mass of 3.663 g, is pressed into a leaf of 2.187 µm thickness, what is the area of the leaf? (b) If, instead, the gold is drawn out into a cylindrical fiber of radius 2.200 µm, what is the length of the fiber? (a) Number i 1.429 Units m^2 (b) Number 72.56 Units
