Asked by Amanda
A 3.78 g sample of ethanol (C2H5OH) was burned completely in a bomb calorimeter. The temperature of the calorimeter plus the contents increased from 25.6oC to 35.2oC.
Knowing that ethanol's heat of combustion is -3600 kJ/mol, calculate the total heat capacity ( in kJ/oC ).

C2H5OH + 3O2 ==> 2CO2 + 3H2O
heat of combustion ethanol = 3600 kJ/mol x (3.78/molar mass ethanol) = ?
? = Ccal(Tfinal-Tinitial)
