Use combustion analysis to determine empirical and molecular formulas (hydrocarbons).\ When

5.428

grams of a hydrocarbon,

C_(x)H_(y)

, were burned in a combustion analysis apparatus, 16.44 grams of

CO_(2)

and 8.415 grams of

H_(2)O

were produced.\ In a separate experiment, the molar mass of the compound was found to be

58.12(g)/(m)ol

. Determine the empirical formula and the molecular formula of the hydrocarbon.\ Enter the elements in the order presented in the question.\ empirical formula
