Pure gold can be made into extremely thin sheets called gold leaf. Suppose that 5.0 x 102 kg of gold is made into gold leaf having an area of 3620 m2. The density of gold is 19.3 g/cm3.
a. What is the thickness of the gold leaf in cm? ...in nanometers?
b. A gold atom has a radius of 1.44 x 10-10 m. How many atoms, stacked on top of each other, make up the thickness of the gold leaf?
