Q. Gold, that has a mass of 19.32g for each cubic centimeter of volume, is the most ductile metal and can be pressed into the thin leaf or drawn out into a long fiber.

(a) If a sample of gold, with a mass of 49.73g, is pressed into a leaf of 1.8µm thickness, what is the area of leaf?

(b) If, instead, the gold is drawn out into a cylindrical fiber of radius 1.5µm, what is the length of fiber?
