a. Given the diameter of the asteroid to be (8.80100)km and the density of the asteroid to be (2.1600100)g/cm3, calculate the total mass of the asteroid in grams. Remember to round your answer to the correct number of significant figures Note: The answer is assumed to be reduced to the highest power possible.(This means that everything is in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm2. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: 10 Answer units b. Given the mass of the asteroid to be (8.3361014) in grams and the diameter dust over the surface of the Earth in grams per square centimeter (g/cm2). Note: The answer is assumed to be reduced to the highest power possible.(This means that everything is in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm2. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: 10 Answer units c. Given the concentration of Iridium in the asteroid in ppm to be (4.65102) and the mass of the asteroid in grams to be (7.3411014), calculate the mass of iridium in kilograms that settled over the surface of the planet. Note: The answer is assumed to be reduced to the highest power possible.(This means that your answer should be in scientific notation) When entering units for the answer, use the symbol for the unit, and if the unit has an exponent, enter the exponent as a carat(^). For example, grams would be "g" and, the unit grams per centimeter squared would look like, g/cm2. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: 10 Answer units d. The "proof" of the asteroid hypothesis is the presence of an elevated level of Iridium in the earth's crust. But which isotope of iridium was found in the Earth's crust? In a particular isotope of iridium, the number of neutrons was found to be 121. Determine the mass number and write the isotopic notation for that isotope. Research the stable isotopes of iridium and indicate if that isotope is stable. If it is unstable, indicate the change it undergoes to become stable. Your
