4. Quinone, which is used in the dye industry and in photography, is an organic compound containing only C, H, and O. What is the empirical formula of the compound if you find that 0.105 g of the compound gives 0.257 g of CO2 and 0.0350 g of H20 when burned completely? Given a molecular weight of approximately 108 g/mol, what is its molecular formula?

Conine (M = 127.23 g/mol), a substance isolated from poison hemlock, contains only carbon, hydrogen, and nitrogen. Combustion of 5.024 mg of conìine yields 13.90 mg COz and 6.048 mg of H2O. What are the empirical and molecular formulas ofconine?

A given compound is analyzed and found to contain only C, H and O. When a 35.79 g sample of this compound is completely combusted in the presence of excess oxygen, the reaction yields 49.19 g of carbon dioxide and 13.43 g of water. What is the empirical formula of this compound?

A compound contains only C, H, and N. Combustion of 35.0mg of the compound produces 53.0mg CO2 and 32.6mg H2O. What is the empirical formula of the compound?

Researchers obtained the following data from experiments to find the molecular formula of benzocaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 3.54 gg sample of benzocaine with excess O2O2 formed 8.49 gg CO2CO2 and 2.14 gg H2OH2O. Another sample of mass 2.35 gg was found to contain 0.199 gg of NN. The molar mass of benzocaine was found to be 165 Find the molar formula of benzocaine. Express your answer as a chemical formula.
