Enthalpy change in reaction

Chemistry Level 1

If 23 grams of ethanol, $$\ce{C2 H5OH}(l)$$ is fully combusted, $$683.4\text{ kJ}$$ of heat is generated. The thermochemical equation for this reaction is as follows:

$\ce{C2H5OH}(l) + 3\ce{O2}(g) \ce{->} 2\ce{CO2}(g) + 3\ce{H2O}(l)$

Find the value of $$\Delta H$$ in terms of $$\text{kJ/mol}$$.

You are given that the molecular weight of $$\ce{C2 H5OH}(l)$$ is 46.
