The enthalpy of combustion of glucose is \( -2808 KJmol ^{-1} \) at \( 25^{\circ} C \). How many grams of glucose do you need to consume [Assume wt \( =70 kg , g =10 m / s ^{2} \) ].
(a) to climb a flight of stairs rising through 5 meters.
(b) to climb a mountain of altitude 5000 meters?
Assume that \( 25 \% \) of enthalpy can be converted to useful work.
