An athlete is given 100g100g100g of glucose (C6H12O6)({C}_{6}{H}_{12}{O}_{6})(C6​H12​O6​) for energy. This is equivalent to 1800kJ1800\mathrm{kJ}1800kJ of energy. The 5050%50 of this energy gained is utilized by the athlete for sports activities at the event. In order to avoid storage of energy, the weight of extra water he would need to perspire is _____g (Nearest integer) Assume that there is no other way of consuming stored energy.

Given : The enthalpy of evaporation of water is 45kJmol−145\mathrm{kJ}{\mathrm{mol}}^{-1}45kJmol−1

Molar mass of C,H&O are 12.112.112.1 and 16gmol−116g{\mathrm{mol}}^{-1}16gmol−1.
