In a small village of 1000 people, a total of 2.0 × 10⁶ kJ of energy is consumed per day. Assume that this energy comes from the combustion of liquid 1-hexanol (C₆H₁₄O). Calculate the mass of liquid 1-hexanol necessary to provide the amount of energy the village needs.

C₆H₁₄O(l) + 9 O₂(g) → 6 CO₂(g) + 7 H₂O(g)

ΔH°_f for 1-hexanol = –377.5 kJ/mol

ΔH°_f for CO₂(g) = –393.5 kJ/mol

ΔH°_f for H₂O(g) = –241.8 kJ/mol
