Chemistry Question from JEE Main 2023 · 6 April, Shift 2

Consider the following data:

Heat of combustion of $\mathrm{H_2(g)}$ = $-241.8 \, \text{kJ mol}^{-1}$

Heat of combustion of $\mathrm{C(s)}$ = $-393.5 \, \text{kJ mol}^{-1}$

Heat of combustion of $\mathrm{C_2H_5OH(l)}$ = $-1234.7 \, \text{kJ mol}^{-1}$

The heat of formation of $\mathrm{C_2H_5OH(l)}$ is $(-)$ _____ $\text{kJ mol}^{-1}$ (Nearest integer).
