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

Determining Empirical Formula

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)

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?
