When 6.104 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 19.15 grams of CO2 and 7.842 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 28.05 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon.
A 7.797 gram sample of an organic compound
containing C, H and O is analyzed by combustion analysis and
7.623 grams of CO2 and
1.561 grams of H2O are produced.
In a separate experiment, the molar mass is found to be
90.04 g/mol. Determine the empirical formula and
the molecular formula of the organic compound.

As with any combustion reaction, the products of combusting a
hydrocarbon fuel (CxHy) with oxygen (O2) are carbon dioxide (CO2)
and water (H2O).
A mass of 16.89 g for an unknown fuel was combusted in
a reaction vessel containing an unknown amount of oxygen. At the
end of the reaction, there still remained 16.85 g of the fuel as
well as 0.0654 g of water and 0.1198 g of carbon dioxide. The
oxygen was completely consumed during the reaction.

A high grade fuel oil which consists of only hydrocarbon, CxHy
is burnt in a combustion chamber at 25 °C. The standard heat of
combustion is -43,515 J/g with CO2 (g) and H2O (l) as products. The
temperature of the fuel and air entering the combustion chamber is
25 °C. The air is assumed dry. The flue gases leave at 300 °C and
their average composition is 11.2 % CO2, 0.4 % CO, 6.2 % O2 and
82.2 % N2...
