What is the value of delta h for the combustion reaction

Reference no: EM13180112

A sample of ethanol, C2H5OH, weighing 2.840g was burned in a colorimeter. The temperature of the calorimeter rose from 25C to 33.73C. If the heat capacity of the calorimeter was 9,630 J/C, what is the value of delta H for the combustion reaction in KJ/mol.
