The standard enthalpy of combustion for methanol is about -726 kJ/mol. To calculate the energy released when 40.0 g of methanol is burned, first convert the mass to moles using the molar mass of methanol (32.04 g/mol). Then, multiply the moles by the enthalpy of combustion to find the total energy released.
