Clausthalite is a mineral composed of lead selenide
(PbSe). The mineral adopts a NaCl-type structure. The density of PbSe at 25C is 8.27g/cm^3. Calculate the length of an edge of the PbSe unit cell in Angstroms.
Converting angstroms to picometers. - An angstrom is a non SI unit of measurement equal to 10^-10m. How many angstroms are equivalent to 259 picometers?
