You have a sample of hydrocarbon of unknown formula. You only know that the molecule contains ONLY C and H. You analyze the hydrocarbon by combusting a 1.230 g sample in excess oxygen to produce CO2 and H2O. You collect 3.726 g of CO2 produced by the reaction. a.) Determine the moles of CO2 produced. b.) Determine the moles and grams of C in the CO2 produced. Note that this is the same as the moles and grams of C in your hydrocarbon sample. c.) Determine the g and moles of H in the hydrocarbon sample. d.) Determine the molar ratio of H to C in your sample. e.) Based upon your calculations above, what is the empirical formula of the hydrocarbon?

You have a sample of hydrocarbon of unknown formula. You only know that the molecule contains ONLY C and H. You analyze the hydrocarbon by combusting a 1.230 g sample in excess oxygen to produce COand H2O. You collect 3.726 g of COproduced by the reaction.

a.) Determine the moles of COproduced.

b.) Determine the moles and grams of C in the COproduced. Note that this is the same as the moles and grams of C in your hydrocarbon sample.

c.) Determine the g and moles of H in the hydrocarbon sample.

d.) Determine the molar ratio of H to C in your sample.

e.) Based upon your calculations above, what is the empirical formula of the hydrocarbon?
