Calculate the molar enthalpy of the reaction:

0.25 moles of a substance is reacted, and the heat released produces a 4.5°C temperature increase in 325 ml of water in a coffee cup calorimeter. (Recall that the specific heat capacity of water is 4.19 J/g°C.)
A) 24,511.5 J/mol
B) 35,733.8 J/mol
C) 44,321.9 J/mol
D) 57,422.2 J/mol
