Assume that the complete combustion of one mole of ethanol to carbon dioxide and water liberates 1370 kJ (?G°\' = –1370 kJ/mol). If the energy generated by the combustion of ethanol is entirely converted to the synthesis of a hypothetical compound X, calculate the number of moles of the compound that could theoretically be generated. Use the value ?G°\'compound X = –54.5 kJ/mol. Round your answer to two significant figures.
