Answer to Question #273457 in Physics for haze

Question

In step 1 above, you calculated how much iridium was required to produce a global layer with an average abundance of iridium of 3 × 10-8 g/cm2 . We will assume that when the asteroid hit Earth it vaporized, blasting fine particles high into the atmosphere. All of the asteroid material, including iridium, was transported around the planet and settled on Earth’s surface within a few years following impact. The asteroid that caused the K-T extinction is thought to have the chemical composition of a carbonaceous chondrite of the C1 group (a C1 chondrite). Based on the information presented, determine the mass of the asteroid needed to supply that amount of iridium. Be sure to convert your answer into kilograms.
