Any alkane on combustion will lead to CO2 and H2O formation.
No. of moles of CO2 formed = 92.63/44 = 2.10 moles
No. of moles of H2O formed = 42.63/18 = 2.36 moles
Moles of octane taken = 30/114 = 0.263 moles
so on taking ration of moles we get for 1 mole of octane we get 8 moles of carbon dioxide and
9 moles of water.
so total number of carbon in octane is 8 and hydrogen is 18.
Molecular formula is C8H18 and empirical formula is C4H9
