The correct answer is Conference committee.
Answer:
The total mass of oxygen is 2.28x10^7 kg, silicon = 1.36x10^7 kg, ruthenium and rhodium = 5x10^-3kg each.
Explanation:
The first thing to do is to solve the total mass of Earth. That is done by multiplying the density with surface area and thickness. The total mass is 5x10^10 kg. The rates given for each compound are equivalent to 1 metric ton. That value is multiplied by the mass of Earth to determine each compound's total mass. The answers for oxygen, silicon and the two rarest non-radioactive elements are 2.28x10^7 kg, 1.36x10^7kg, 5x10^-3, respectively.
