Question

A 35.6 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter, according to the following reaction.  If the temperature rose from 35.0 oC to 76.0 oC and the heat capacity of the calorimeter is 23.3 kJ/oC, what is the value of  ΔHrxn (in kJ/mole of C2H5OH)?  The molar mass of ethanol is 46.07 g/mol.
