If a 20-g sample of platinum has the volume of 4.67mL, what is the density of the platinum in g/cm3?
Platinum was first mined commercially in South Africa.But it is found in various amounts in gold ores, so that yellow gold in Ancient Egypt contains platinum, and white gold in pre-Columbian Ecuador had significant platinum content. It was from South America that Antonio de Ulloa identified platinum as a separate metal, although alloys were studied by William Brownrigg and Charles Wood as early as 1741. A malleable form of the metal was prepared by Carl von Sickingen in 1772.
