question

(a) If a rocket were fueled withkerosineand liquid oxygen, what weight of oxygen would be required for every liter of kerosine ? (Assumekerosineto have the average composition of n-C_14H_30 and a density of 0.764 g/ml). (b) How much energy would be required to fragment the molecules in one liter ofkerosine? (Assume 157 kcal mole for each -CH_2- group and 186 kcal mole for each -CH_3- group.)
