An athelete is given 100 g of glucose (C6H12O6) of energy equivalent to 1560 kJ. He utilises 50 percent of this gained energy in the event. In order to avoid storage of energy in the body, the weight of water he would need to perspire is- (The enthalpy of evaporation of water is 44 kJ/mole.)
Text Solution
Verified by ExpertsThe correct answer is:
A
Given energy = 1560 kJ
Utilised energy = 
= 780 kJ
44 kJ Utilised energy for evaporation of H2O = 18 gram
780 kJ Utilised energy for evaporation of H2O
= 
× 780 = 319 gm
