An athlete is given 100 g of glucose (`C_6H_12O_6`) of energy equivalent to 1560 kJ. He utilises 50% of this gained energy in the event. In order to avoid the storage of energy in the body, calculate the weight of water he would need to perspire. The enthalpy of evaporation of water is `44 kJ mol^(-1)`.

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Calculate the energy utilized by the athlete
The athlete is given 100 g of glucose, which provides 1560 kJ of energy. He utilizes 50% of this energy.

\[ \text{Energy utilized} = \frac{50}{100} \times 1560 \, \text{kJ} = 780 \, \text{kJ} \]
