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 8.464 g, is pressed into a leaf of 5.036 ìm thickness, what is the area (in m2) of the leaf? (b) If, instead, the gold is drawn out into a cylindrical fiber of radius 2.000 ìm, what is the length (in m) of the fiber?

• physics -

8.464/density= area*thickness

solve for area, watch units. I am uncertain of you leaf thickness.
