There is an old story about a king and his crown. the king hired a goldsmith to make him a crown a pure gold. after the king received the crown, he started to worry that the goldsmith might have cheated him. he thought maybe the goldsmith didn't use pure gold, maybe he used a mix of metals to save money. the king asked a man named archimedes to figure out if the crown was pure gold or not. archimedes reasoned that the density of a lump of gold and a crown of pure gold would be the same. how could he prove if that crown was pure gold without melting or otherwise destroying the crown?

Legend says that archimedes, in determining whether or not the king's crown was made of pure gold, measured its volume by the water displacement method. if the density of gold is 19.3 g/cm3, and the crown's mass is 600 g, what volume would be necessary to prove that it is pure gold?

Legend says that archimedes, in determining whether or not the king’s crown was made of pure gold, measured its volume by the water displacement method. if the crown weighs 600 gm in air, what would its "weight be in water", necessary to prove that it is pure gold?

Archimedes (287-212 bce) was a greek scientist with many accomplishments. he is best - known from the legend of solving a problem given to him by king heron ii of syracuse (sicily).the king suspected that his crown, which was supposed to be made from pure gold, contained some silver alloy, and he asked archimedes to prove or disprove his suspicion. (it turned out the crown did contain silver.) according to a roman account, while pondering a question archimedes went to the baths and as he noticed the water flowing out upon immersion, he recognized a solution to the problem and run home shouting "eureka! " (greek for "i have found it.") it has also gotten him thinking about buoyancy, and the buoyant force, responsible for some objects' ability to float, is named after him. how would you experimentally determine whether or not the crown was pure gold?
