The price of gold is 3.125 grams. 1 money gold is equal to 3.125 grams. 1 money is used in the measurement unit of traditional Chinese medicine and gold. 1 catties is equal to 16 two, 1 catties is equal to 500 grams, 1 two equals 10 money, and the calculation method of money converted into grams is 500 ÷ 16 ÷ 10, which is equal to 3.125, so 1 money is equal to 3.125 grams. This information: ⑴ The color of gold is golden yellow, metal luster, difficult to decompose. The density is 19.3g/cm3, and the melting point is 1064.4 ° C; it has good ductility and can be pressed into thin foil. It has extremely high heat transfer and conductivity. The resistance of pure gold is 2.4P. Pure gold has good anti -chemical corrosion and is the best electroplating material. : As a precious metal, gold has good physical characteristics. "Real gold is not afraid of fire" is that the chemical stability of gold is very high. It is not easy to have chemical reactions with other substances. Do not worry about oxidation and discoloration. Even in the melting state, it will not be oxidized and discolored. The density is strong and the feel is heavy. Good toughness and ductility, good guidance. Pure gold has gorgeous yellow, but after incorporating other metals, the color changes greatly. For example, gold and copper alloy are dark red, and the silver alloy is light yellow or gray -white. Jin Yi was grinded into powder, which is why Jin is scattered in nature. Pure gold jewelry is also easily worn and reduced. Court of gold in the Golden Table in the Menjiev cycle table is 79, that is, the atomic nucleus of the gold contains 79 protons, and the proton belt is positive. At the same time, due to the conformity of half full rules, gold has good chemical stability. In the metal market, metals such as crickets, 铑, 钯, 锇, 铱, and platinum are collectively referred to as precious metals. 虽 gold is a very soft metal, but it is not as good as lead and tin metal. Use nails on pure gold to draw traces. This softness makes gold very easy to process. However, this point is not ideal for the maker of the decoration, because it is easy to make the decorations hurt and make it make it make it wound and make it it. Lost luster and even affect beauty. Therefore, when making jewelry with gold, copper and silver are generally added to improve their hardness.
