摘要：
The molar enthalpies of solution of HfMo2Og, Mo and HfF4 in (10 mol HF(aq) + 4.41 mol H2O2(aq)) dm(-3) have been measured using an isoperibol type calorimeter. From these results and other auxiliary data, the standard molar enthalpy of formation of HfMo2O8(s) has been calculated to be Delta(f)H(m)(298.15 K) = -2605.8 +/- 5.9 kJ mol(-1). This value of enthalpy of formation of HfMo2O8 is consistent with the second law enthalpy of formation of HfMo2O8 determined in this laboratory by transpiration technique.
