An average person needs about 10000 kJ energy per day. The amount of glucose (molar mass = 180 . 0 g mol - 1 ) needed to meet this energy requirement is ______ g . (Use : Δ C H (glucose) = - 2700 kJ mol - 1 )

Step-by-step solution

1 mole glucose give 2700   kJ energy so mole of glucose needed for 10 4   kJ energy = 10000 2700 = 3 . 7037   moles wt. of glucose = 3 . 7037 × 180 = 666 . 666 ≈ 667 gm
