# 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.
