Earth’s surface area is 5.1 x 108 km2, its crust has an average thickness of 35 km and an average density of 2.8 g/cm3. The two rarest (non-radioactive) elements in the crust are ruthenium and rhodium, each with an abundance of 1.0 x 10-4g/metric ton crust. What is the total mass of these two elements in the earth’s crust? (1g = 1 x 10-6 metric ton)
