Question: the asteroid 97 klotho is classified as a type m...

Question details

The asteroid 97 Klotho is classified as a type M asteroid, meaning it appears spectroscopically to be composed partially of FeNi metal. 97 Klotho has a total bulk mass of 1.3 x 1018 kg. The density of meteoritic FeNi metal is 7.9 g/cm3. Iron meteorites contain an average Pt concentration of 10 parts per million (10 g Pt per 106 grams of sample). Assume the composition of 97 Klotho to be 10% FeNi with a composition similar to iron meteorites, and the rest a mix of silicate rock that contains no mineable platinum. Given these values, what total amount of platinum, in millions of metric tons (1,000,000,000 kg), would exist within the mass of the asteroid 97 Klotho?
