  1. What formula is there? Thank you ~ Story of Time Answer: 1 Popularity: 1 Solution Time: 2008-07-08 09:11 Report Satisfaction Answer 1. Full water in the cup (know the total volume V of the water), hang the platinum with thin line on the cup with the cup In the middle, wait for it to be completely immersed in
    2, see how much water of water in the cup, V1, then the volume of platinum is (V-V1)
    3, use electrons to quantify platinum. The density of the mass is M
    4, and the density of platinum is = m/(V-V1). In the density table of platinum, to see if it is a pure platinum platinum and platinum is a precious metal that is naturally white. The annual mining volume of platinum is only one -twenty of gold, and a ounce of platinum needs to be refined from 10 tons of platinum ore. Domestic platinum jewelry usually contains 90 % of pure platinum and is attached to the "PT900" logo. Platinum white gloss is naturally natural, and long -term wearing will not fade. The hardness of platinum makes it the best friend of diamonds.
    Platin is generally used on jewelry in 1898. Louis Cosesi, France, said: "Platinum is the king of precious metals." Erdi, his large number of platinums caused by platinum, and laid the impression of the world's "best jewelry jewelry to use platinum".
    The reason why platinum is called the king of valuable metals
    Kuridy noticed that the platinum viscosity is super strong, and even a small inlaid seat can firmly support the gemstone. The smaller the inlaid, the more you can see the gemstone clearly, and it will not be the excess color of the gemstone like gold.
    The platinum although it will be melted in the water (mixed liquid formed by concentrated nitric acid and concentrated hydrochloric acid), but in addition, it is not affected by any material. It will not deteriorate when you encounter mercury like gold. This persistent and elegant white light is the reason why it is called the king of precious metals and is chosen as a wedding ring.
    This with high purity
    Platinum is represented by PT. Platinum used to be used as jewelry is mainly PT900 and PT850. This means that they contain 90%and 85%of platinum, respectively. In Japan, if PT is less than 850, it is not called platinum. The purity of 18K gold is 75%, which shows that the purity of platinum is high. In the UK, only PT950 is marked as platinum.
    , even if there is a PT900 mark on the inside of the ring, it cannot guarantee its quality. Conscience shops are engraved with government inspection qualification signs. In addition, some stores are engraved with unique quality assurance marks, and consumers are best to buy from these credit stores.
