SUMMARY
The discussion focuses on calculating the empirical formula of a hydrocarbon based on the combustion of a 7.81 g sample, which produced 26.4 g of CO2. The conversion of carbon in the hydrocarbon to CO2 during combustion is clarified, indicating that the mass of CO2 reflects the amount of carbon present in the original sample. The empirical formula can be determined by analyzing the ratio of carbon to hydrogen in the hydrocarbon. The correct empirical formula options provided include CH, C2H10, and others, with the process of combustion being essential for the calculation.
