Suppose the Brain Needs to Metabolize About 4 G Glucose $\to$

Suppose the brain needs to metabolize about 4 g glucose (C₆H₁₂O₆,180 g/mol) per hour.Assuming glucose metabolism can be approximated by the reaction below,about how much energy does the brain use per day? C₆H₁₂O₆(g) + 6 O₂(g) $\to$ 6 CO₂(g) + 6 H₂O( ) $\Delta$ H_comb = -2808 kJ/mol

A) 700 kJ
B) 1500 kJ
C) 8400 kJ
D) 11,000 kJ
E) 17,000 kJ
