Calculate the Standard Enthalpy of Formation of Liquid Methanol, CH₃OH(l) $\rarr$

Calculate the standard enthalpy of formation of liquid methanol, CH₃OH(l) , using the following information: C(graph) + O₂ $\rarr$ CO₂(g) $\Delta$ H° = -393.5 kJ/mol
H₂(g) + (1/2) O₂ $\rarr$ H₂O(l) $\Delta$ H° = -285.8 kJ/mol
CH₃OH(l) + (3/2) O₂(g) $\rarr$ CO₂(g) + 2H₂O(l) $\Delta$ H° = -726.4 kJ/mol

A) -1,691.5 kJ/mol
B) -238.7 kJ/mol
C) 1691.5 kJ/mol
D) 47.1 kJ/mol
E) -47.1 kJ/mol
