The massic energy of combustion of crystalline acetylsalicylic acid was determined in an NIST adiabatic-aneroid-rotation bomb calorimeter. The standard molar enthalpy of combustion at T = 298.15 K and p o = 10 5 Pa is c H o m (C 9 H 8 O 4 , cr, 298.15 K) = -(3926.71 ยฑ 0.34) kJ โข mol -1 . The derived
