Calculate the formula of the hydrated salt that was formed the molecular weight of the anhydrous salt (mgso4) is 120371 g/mol best answer - chosen by voters ok, let's subtract out the mass of the crucible to see how much salt we have before: 15246 - 12125 = 3121g hydrated salt after: 13650. To do this i plan to work out the amount of water a set mass of hydrated copper sulphate loses when it becomes anhydrous i will work this out by 0008g solving to find x in (cuso4 � xh2o) is now a simple matter of deducing the amount in moles of each compound, and finding the simplest integer. If you heat a hydrated salt, you can cause the water it contains to evaporate the resulting crystal is called the difference in mass between the anhydrous and hydrated salt gives you the information you need to find the for example, the chemical formula of anhydrous copper (ii) sulfate is cu(so4. Here's an example of how to do this: let's assume you want to determine the formula for the hydrate of barium chloride you then heat the sample in order to remove the water and find the weight of the anhydrate to be 352 here is a video discussing how to find the empirical formula of copper sulfate.

Formulas chemistry formulas thermodynamics formulasheat of hydration formula the enthalphy of a hydrated salt is the change in heat content, when 1 mole of an anhydrous substance combines with the requisite number of molecules of water to form the hydrate. Determination of empirical formulas in this lab you will synthesize zinc iodide from zinc metal and you will also determine the formula of an unknown hydrate stockroom you will need a hot plate this is the empirical formula of your unknown first, find moles of water driven from your sample. To create zinc iodide, we put both zinc and iodine in an erlenmeyer flask and dissolved the iodine with ethanol the iodine represented the limiting reagent the theoretical yield and actual yield was found to produce the percent yield, which came out to be 9706% and lastly the percent recovery was.

3) a hydrated carbonate of an unknown group 1 metal has the formula x2co3Ÿÿ10h2o and is found 4) a teacher told a student that the amount of hydrated salt in lansfordite was 0030 mol, and that calculate the number of moles of water of crystallisation in the zinc sulphate sample given that. Zinc chloride is the name of chemical compounds with the formula zncl2 and its hydrates zinc chlorides, of which nine crystalline forms are known, are colorless or white, and are highly soluble in water zncl2 itself is hygroscopic and even deliquescent. Formula and structure: zinc chloride chemical formula is zncl2 and its molar mass is 13615 g mol-1 the zinc chloride molecule is a binary salt formed by the zinc cation zn+2 and chloride anion cl- and it can be found as the structure may be tetrahedral or orthorhombic depended on the hydration state.

Calculations to find the formula of hydrated zinc sulphate mr of zinc sulphate znso4 = 65 + 32 + (16 x 4) =161 mass of water in 1 mole of znso4 finding the formula of magnesium oxide aims when magnesium is heated in air, it reacts with oxygen during this oxidation reaction, magnesium. Free essay: experiment 9 empirical formula of zinc iodide objectives upon completion of this experiment, students should have learned: 1 the law the masses of the starting materials, products and leftover starting material will enable you to calculate the formula of the zinc iodide produced. And finding the formula of a hydrated salt of known formula but unknown water content hydrated salts are characterized by the number of moles of water molecules per mole of salt the formula of this hydrate shows the molar amount of water incorporated into the crystal matrix. The mass of the hydrated salt obtained was 721 g what hydrate is it problem #7: a substance was found to have the following percentages by mass: 23% zinc what is the empirical formula problem #8: a 500 g sample of hydrated barium chloride, bacl2 nh2o, is heated to drive off the water.
