An athlete is given 100 g of Glucose
(C_6 H_12 O_6) of energy equivalent to 1560 kJ. He utilises 50 % of this gained energy in the event. In order to avoid storage of energy in the body, calculate the mass of water he would need to perspire. The enthalpy of evaporation of water is 44 kJ/mole.

Energy from 100 g of Glucose = 1560 kJ
Energy not used = 1560 * (50/100) = 780 kJ
(we must use this excess energy to convert water into vapours to avoid storage)
Amount of water = 780/44 = 17.73 mol
Mass of water to be perspired
= 17.73 * 18 = 312.48 g
18 is the molecular weight of water.
