A bomb calorimeter is calibrated by burning 1.6390 g of benzoic acid (C6H5COOH) with the specific heat of combustion –ΔU = 26424 J/g, whereby the temperature rises by 1.8363 K. When burning 1.3471 g of palmitic acid (C15H31COOH) the temperature rises by 2.2319 K. The test temperature in both cases was approx. 298.15 K. Find palmitic acid's molar enthalpy of formation ΔH.
