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
