An athelete is given `100g` of glucose `(C_(6)H_(12)O_(6))` of energy equivalent to `1560 kJ`. He utilises `50%` of this gained enegry in the event. In order to avoid storage of enegry in the body, calculate the weight of water he would need to perspire. The enthalpy of evaporation of water is `441kJ//mol`.

Options

A. 319 gm
B. 422 gm
C. 293 gm
D. 378 gm

Answer
