Assume that the complete combustion of one mole of ethanol to carbon dioxide and water liberates 1370 kj of energy (δ°′=−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 δ°′compound x=−45.9 kj/mol . round your answer to two significant figures.
