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`.

Explanation

To solve the problem step by step, we will follow the given information and perform the necessary calculations.

### Step 1: Calculate the energy utilized by the athlete
The athlete is given 1560 kJ of energy from 100 g of glucose. Since he utilizes 50% of this energy, we can calculate the utilized energy as follows:

\[ \text{Utilized Energy} = 50\% \times 1560 \, \text{kJ} = 0.5 \times 1560 \, \text{kJ} = 780 \, \text{kJ} \]
