[Given : Molal depression constant and density of water are $1.86\, K\, kg\, mol^{-1}$ and $1\, g\, cm^{-3}$ respectively.]
$C_2H_5OH_{(l)}+{3O_2} _{(g)} \rightarrow 2{CO_2} _{(g)}+3{H_2O}_{(l)}$
the amount of heat produced as measured in bomb calorimeter, is $1364.47\, kJ\, mol^{-1}$ at $25\,^oC.$ Assuming ideality the enthalpy of combustion, $\Delta_CH,$ for the reaction will be : $(R = 8.314\,kJ \,mol^{-1})$ .....$kJ\, mol^{-1}$
