The metabolic oxidation of glucose, C6H12O6, in our body produces CO2, which is expelled from our lungs as a gas: C6H12O6(aq) + O2(g) → CO2(g) + H2O(g) If 11.8 L of dry CO2 was produced at a slightly elevated body temperature (39°C) and 902 mm Hg, what mass of glucose was oxidized?
Moles of CO2 produced = n= pv/RT
P= 902/760= 1.18 atm
n= 1.18* 11.8/0.0821*312
n= 0.543 moles.
I mole of glucose produces 6 moles of CO2so moles of glucose used= 0.543/6= 0.0905 moles
Mass = 180*0.0905= 16.29 gm
