Show your work for your calculations. Mass of crucible + lid Mass crucible + lid+ hydrate Mass of hydrate Mass of crucible + lid + anhydrous salt Mass of anhydrous salt Mass of water in hydrate Mass % water in hydrate Formula of anhydrous salt Molar Mass of the anhydrous salt Moles of water in hydrate Moles of anhydrous salt in hydrate Value of x Formula of hydrate Conclusion: 13.200 g 15.206 g bo 14.485 g g g % CuSO4 g/mol Questions: 1. True or False: The hydrate is the salt that remains after heating. 2. True or False: The anhydrous salt does not contain water. 3. The hydrate salt was heated and the weight after heating was determined to be 3.894. Is this the mass of the hydrate salt or of the anhydrous salt? 4. Given the following grams of the substances, what is the percentage of C in the compound? • Mass of C = 2.402 g Mass of the compound = 10.304 g 5. Given the following grams of the elements, what is the empirical formula of the compound? • 2.45 g Si 12.4 g Cl Show your work for your calculations.
