Earth’s surface area is 5.10x10^8km², and its crust has amean thickness of 35 km and mean density of 2.8 g/cm3. Thetwo most abundant elements in the crust are oxygen (4.55x10^5g/metric ton, t) and silicon (2.72x10^5g/t), and the two rarest non-radioactive elements are ruthenium and rhodium, each with anabundance of 1104g/t. What is the total mass of each of theseelements in Earth’s crust (1 t =1000 kg)?
