1440 kJ of heat is evolved.

C_6H_(12)O_(6)(s)+6O_(2)(g)rarr6CO_(2)(g)+6H_2O_((l))

DeltaH=-2806 kJ.mol^(-1)

I will assume the glucose is INXS so:

6 mol O_2 produce 2806 kJ

M_r of O_2 = 16 +16 = 32

So 1 mol O_2 weighs 32g

So 6 x 32 = 192g O_2 produces 2806 kJ.

So 1g O_2 produces 2806/192 = 14.6 kJ

So 98.6g O_2 produces 14.6 x 98.6 = 1440 kJ
