When 1.00g germanite as treated this way, the germanium presented was totally converted into the 0.177g of a chloride which is having 33.9% by mass of germanium. Determine the percentage of germanium in germatite. When the element germanium was once an important component of transistors. It can be made by heating the ore germanite with hydrogen chloride, distilling of the germanium chloride to the oxide to the metal.
