In the laboratory a student burns a 1.17-g sample of dimethyl oxalate (C4H6O4) in a bomb calorimeter containing 1070. g water. The temperature increases from 24.60 °C to 27.70 °C. The specific heat capacity of water is 4.184 J g-1 °C-1.

The combustion enthalpy is −1675 kJ/mol dimethyl oxalate.

  • C4H6O4(s) + 7/2 O2(g) 4 CO2(g) + 3 H2O(l) ΔrH o = -1675 kJ/mol

Calculate the heat capacity of the calorimeter.

heat capacity of calorimeter = J/°C
