Complete combustion of 17.12mg sample of xylene in oxygen yielded 56.77mg of co2 and 14.53mg of h2o. Determine the empirical formula of xylene

 

Example 3.7 C Determine the Empirical Formula from Combustion Data A Combustion device was used to determine the empirical formula of a compound containing ONLY carbon, hydrogen, and oxygen. A 0.6349 g sample of the unknown produced 1.603 g of CO2 and 0.2810 g H20. Determine the empirical formula of the compound.

Perchloroethylene, also known as perc. is the solvent used in most dry cleaning? It consists of C and Cl. Determine the empirical formula of perchloroethylene given that a 2.58-g sample field 1.37 g CO_2 in a combustion analysis experiment. Add subscripts to complete the empirical formula. CCl

Complete combustion of 4.40 g of a hydrocarbon produced 14.1 g of CO_2 and 5.04 g of H_2O. What is the empirical formula for the hydrocarbon?
