Question

Chemical synthesis of many different types of nanoparticles can commonly yield 200 mg of nanoparticles. The density of Pt is 2145 g/em. (a) What number of Pt nanocubes with edge lengths of 10 nm would have a total mass of 200 mg? (The mass of any surface coatings on the nanoparticles, if present, is neglected in this calculation.) b) Consider deposition of a uniform thin film of Pt with height of 10 nm and a mass of 200 mg. What surface area is covered by this thin film?
