1 Fabrication shops and machine shops have overlapping capabilities, but fabrication shops generally concentrate on metal preparation and assembly as described above. 2  By comparison, machine shops also cut metal, but they are more concerned with the machining of parts on machine tools.
A hydrated salt is a solid that includes water molecules within its crystal structure A student heated a 9.10-gram sample of a hydrated salt to a constant mass of 5.41 grams What percent by mass of?nhydrous is the term for a hydrate with water heated off. when a  hydrated salt is heated, it loses water of crystallization leaving  an anhydrous salt. Edit. Share to: Answered.
After heating for several minutes the mass of the anhydrate is found to be. 3.56 g. Use this information to determine the formula for the hydrate. - find the mass of the water driven off: mass of hydrate â mass of anhydrate = mass of water. 4.72 g â 3.56 g = 1.18 g. - convert the mass of anhydrate to moles:
