4. Azulene is a beautiful blue hydrocarbon, CxHy. If 0.106g of the compound is burned in oxygen, 0.364g of carbon dioxide and 0.0596g of water are isolated What is the empirical formula? If the Molar mass of the compound is 128.2 g/mol, what is the molecular formula?

5. Determining Empirical Formula

7. In the reaction below, how many grams of PCl 3 can be produced from the reaction of 1.00 g P 4 with 1.00 g Cl 2 ? P 4 (s) + 6 Cl 2 (g)  4 PCl 3 (g)

8. Aspirin is produced by the reaction of salicylic acid (138.1 g/mol) and acetic anhydride (102.1 g/mol). C 7 H 6 O 3 (s) + C 4 H 6 O 3 (l)  C 9 H 8 O 4 (s) + C 2 H 4 O 2 (l) If 1.02 g of C 9 H 8 O 4 (180.2 g/mol) is produced from the reaction of 3.00 g C 7 H 6 O 3 and 5.40 g C 4 H 6 O 3, what is the percent yield?
