Problem- When 2.094 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 7.191 grams of CO2 and 1.178 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 128.2 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon.
Please illustrate work and walk me during the problem so that I can follow and understand it.
