14-65. When 2.50 grams of oxalic acid, H₂C₂O4(s), are
burned in a bomb calorimeter that has a total heat
capacity of 8.75 kJ.K¹, the temperature increases by
0.780 K. Calculate the standard molar enthalpy of
combustion of oxalic acid. Assume AHxn~ AUrxn. Using
this result and the AH values for CO₂(g) and H₂O(l)
given in Table 14.3, calculate the molar enthalpy of
formation of oxalic acid at 25°C.
